MILWAUKEE (CBS 58) -- Many are calling on the Milwaukee Police Department to terminate one of their officers charged in the death of Joel Acevedo, but the department says it's not up to them.

A statement from the Milwaukee Police Department says as of May 19, the Milwaukee Fire and Police Commission is the only entity that has the authority to terminate the officer for his off-duty actions.

Officer Mattioli, a 13-year member of the department, was charged in the death of 25-year-old Acevedo. Investigators say the two were involved in an altercation at Mattioli's home on April 19 -- who was off-duty at the time -- and Acevedo was left unconscious. Acevedo died less than a week later.

Here's a breakdown of events from Milwaukee police:

On April 19, 2020, the day this incident occurred, MPD took extraordinary steps to maintain the integrity of the investigation while keeping the trust of the community. Prior to arriving at the scene on the morning of the incident, Chief Alfonso Morales had already requested that the criminal investigation be handled by the Milwaukee County District Attorneys Office to avoid any appearance of bias. In addition, the Wisconsin State Crime Lab, an outside and independent agency, conducted the crime scene investigation. That same day, Officer Mattioli was arrested.

On May 13, 2020, the Milwaukee County District Attorneys Office issued a criminal complaint for 1st Degree Reckless Homicide charges against Mattioli. The Milwaukee Police Department immediately requested the investigatory materials. Until receiving those investigatory materials, MPD could not fully conduct its internal investigation.

On May 19, 2020, the Milwaukee Fire and Police Commission issued a press release stating it had informed MPD to cease all current investigations regarding Officer Mattioli, and that my Office [FPC] will be taking control of the investigation moving forward. MPD immediately ceased its internal investigation and provided the FPC its requested documents.

According to a news release, MPD says they understandthe community is seeking immediate resolution of Officer Mattioli's employment matter given these extraordinary times.

The release goes on to say, "However, per state law, no member of MPD may be discharged or suspended for more than 30 days without the Department first finding just cause. In order to determine if there was just cause, MPD could not render discipline until the criminal investigation was completed and the investigatory materials were provided to the Department. MPD was actively investigating the internal investigation, and awaiting additional investigatory materials, at the time the Fire & Police Commission took over this disciplinary matter."

Researchers from the UK-based Teeside University, have used 3D printing and scanning techniques to advance a key aspect of forensic investigation: Physical Fit Analysis (PFA). Utilizing and comparing two different 3D imaging methods, the research team were able to recreate human bone fragments for use within the PFA process. Not only could this prevent unnecessary damage from occurring to genuine evidence during a Crime Scene Investigation (CSI), but it may also expand on the forensic applications of 3D printing.

Fused Filament Fabrication (FFF) 3D printing proved to be an accurate and useful method for creating physical replicas of the bone fragments, to perform physical fit analysis (PFA) and bone fragment reconstruction. We therefore recommend CT imaging paired with FFF 3D printing, as an excellent option for non-destructive physical fit confirmation, when working with small fragments and burned bone, said the research team.

Physical fit analysis in Crime Scene Investigation

CSI often requires investigators to examine a range of items as evidence, including human remains, some of which may be damaged or fragmented as a result of the trauma suffered during the event. These remains routinely go through PFA to determine whether they fit together. If this process leads to a positive physical fit, it could place suspects at the scene of a crime, or facilitate object reconstruction that potentially solves the case. Nonetheless, PFA involves a great deal of matching and manual handling, which can lead to the fragments becoming damaged during the process.

Moreover, there are instances where PFA can be extremely challenging, such as when fragments may pose a biological hazard, be extremely small, or the bone itself may be too fragile to move. Considering that the reconstruction process usually involves gluing the parts back together, this can cause problems, and prevent investigators from fully understanding the nature of the trauma. This makes certain-shaped bones difficult to document or present, particularly with those fragments that are three dimensional and complex in nature, or embedded in an external material. As a result, two-dimensional representations of such physical fit results are not always sufficient for presentation in courts or interpretation by experts.

While 3D scanning and modelling have been used in a range of forensic anthropology applications, the handling and reconstructing of bone fragments remains an issue. For instance, 3D modelling is currently used in dismemberment, weapon matching, craniometrics and facial reconstruction cases. Volume scanning has allowed for high resolution images to be obtained, on the nanometre scale in some instances, but they tend to be expensive, time consuming and require specialist expertise and software to operate. Surface scanning methods, on the other hand, tend to be cheaper, and more user-friendly, and are often used for postmortem quantitative injury analysis, landmarking, and the analysis of soft tissue injuries.

Additive manufacturing meanwhile, has proved accurate enough to produce dental models for aiding in maxillofacial surgery. Studies have also demonstrated the applicability of 3D printing for the visualisation and analysis of forensic evidence, and the researchers set about combining the technologies to create 3D printed skull fracture replicas. These 3D models offer the potential for PFA to take place without having to excessively handle the original evidential fragments, while minimising any damage or contamination risks. In addition, such models offer 360 degree visualisation in an engaging and understandable format, that could be used to improve jury comprehension during trials.

3D printing skull fragment replicas

The researchers compared Micro Computed Tomography (CT), a volume scanning technique, with structured light scanning (SLS) a surface scanning technique, to assess the pros and cons between the two methodologies. In order to test their potential for conducting PFA, the team 3D printed two models of burnt bone fragments, to simulate the damage that might be encountered in a genuine investigation.

Modelled on an archaeological human femur donated by the University of Portsmouth, the replicated bone samples were cut and burned in a Gallenkamp Muffle Furnace at 600C for 3060 minutes. Each section of bone fragmented longitudinally, naturally, into at least two separate pieces, either during the burning process or during cooling. The two adjoining fragments were 3D imaged and printed to evaluate the techniques for their use in visualising and analysing the physical fit of burned bone fragments.

The SLS scanner used for testing was a Shining 3D EinScan Pro+, while the larger CT ZEISS Xradia 520 Versa scanner was also chosen, due to its simple setup and non-destructive process. After scanning, the fragments were 3D printed with a FFF Prusa i3 desktop printer, using PLA filament. The optimal print quality (0.15 mm) was selected, and infill levels were set at 0% to create a completely hollow print. PFA was then conducted on the pairs of 3D printed bone models, with accuracy determined on the basis of feature matching and alignment between the two fragments, as well as the haptic feel of the fit.

3D printing was found to preserve a high level of detail for both the CT and SLS models, and overall, the prints produced were of a sufficient quality to perform PFA. Based on the fit quality criteria set out by the team, the confirmation of physical fit was found to be easier using the CT prints compared with the SLS prints. Moreover, in all fragment pairs created, the CT models offered a closer and more robust fit, producing surface structures in greater detail, which was found to be of value in feature matching.

As a result, the researchers concluded that FFF 3D printing could be utilized to produce bone fragment replicas to a sufficient level of detail that either 3D scanning technique could be used. In addition, the team suggested that Selective Laser Sintering (SLS) 3D printing could prove to be a more efficient method of producing the models in future research, by negating the need for support structures used during FFF production. While it could ultimately prove more costly to implement, SLS printing would also result in a higher surface finish, according to the team. Additionally, the successfully reproduced bone fragments could open new applications for 3D printing in other aspects of the PFA process.

The application of 3D imaging and printing for PFA has many advantages compared with traditional methods. Virtual reconstruction of highly fragmented, fragile, and potentially embedded remains, offers an opportunity to generate full reconstructions without compromising the original bone fragments, concluded the researchers.

Furthermore, 3D prints from particularly small fragments or bones with micro-scale details can be isometrically scaled up, generating 3D replicas to visualise fit and perform PFA on items that previously would have been extremely challenging.

Additive advances in CSI

3D scanning and printing technology have been used in a range of ways to assist in CSI applications in recent years.

The Abu Dhabi Police Agency for example, have launched an additive manufacturing initiative to help solve crimes. Using 3D printing, the police force could produce dioramas that enable them to thoroughly assess a crime scene, or be summarily used to communicate a series of events in a court setting.

Police officers in Cascade County, Montana have started using FARO Focus 3D Laser Scanners to survey crime scenes. Capable of taking a full sweep of the scene, the 3D scanner potentially cuts down the personnel needed to record images by up to 80%.

Similarly, the UK-based West Yorkshire Police (WYP) force has installed a DeltaWASP 40 70 Industrial 3D printer at its Wakefield HQ. The machine is also used by its Regional Scientific Support Unit (SSU) in the recreation of crime scenes.

The researchers findings are detailed in their paper titled Reconstruction and physical fit analysis of fragmented skeletal remains using 3D imaging and printing published in the Forensic Science International journal. The report was co-authored by Amber J.Collings and Katherine Brown.

Word is one of the San Francisco police brass who was in involved in managing crowd control during the recent George Floyd demonstrations took his police car home, only to have it stolen along with his riot gear.

Police spokesman Adam Lobsinger confirmed that on Wednesday. an off-duty officer reported that his unmarked vehicle had been stolen in the Marina District.

According to the police burglary bulletin, the gray, 2017 Ford Fusion was equipped with a police radio and that an SFPD jacket, a 26-inch baton and a riot helmet were inside the vehicle at the time of the theft. There were no firearms in the car, Lobsinger said.

The next evening the hot police car was found on the 2800 block of Vallejo Street in Cow Hollow.

No items appeared to be missing from the vehicle. The vehicle was towed to CSI (crime scene investigation) for processing, Lobsinger said. We are not releasing the name of the officer for officer safety purposes.

In fact, marketing segmentation is inclusive in most strategies. When a marketer loses all hope, all that they need is a good plan to relook at how they have segmented their audience who, where, age group etc its a sure fix!

With the introduction of the Fourth Industrial Revolution, there has been improvement in the way that marketers create messages. From hardcopy ads, to digital billboards, to personalised digital marketing the change has affected almost every aspect of the world of marketing.

media updates Nakedi Phala reveals the most relevant segmentations that marketers should consider in their strategies.

Marketing segmentation is the compass in your marketing strategy; it tells you who your possible consumer is, why you should go for them and whether or not they will welcome your product or service.

Without wasting any time, lets head into the three vital marketing segments:

Well, those days are gone. Now, theres the Internet! If you need a car, you can find one and even complete the actual transaction through your smartphone device. But what does this mean for marketers? Well, a marketing team working in the motoring industry can now use smart tech to choose their target buyers by their region or climate, allowing them to find an audience that best suits their vehicles compatibility. This way, they dont need to fit their cars with snow features if it comes to a country like South Africa; so theres an opportunity to save manufacturing costs in this regard.

It is good to think things through again and again before creating a product that might flunk in certain regions, simply because it does not synchronise with your audiences lifestyle.

Once you have learnt your audience's behaviour, you can move swiftly into creating a personalised marketing strategy that will help you understand what kind of conversation you need to create to capture your current and prospective consumers, as well as play right to their likes, needs, interest and routine behaviors.

Audience behavioural patterns need to be forecasted on a long-term basis, as people tend to outgrow certain things. In this regard, its important to keep identifying trends that can give you insight so that you can plan effectively for the future.

Understanding behavioural segmentation has benefits such as:

For example, before a person buys a house, they have a picture in their mind of the type of house they are looking to buy. Whichever house the buyer chooses must fit the image they have in their mind and give them that sentimental feeling.

So, what does this mean for marketers? Well, it means that you need to tap into your consumers emotions, thoughts and desires in order to understand what they need. Once you understand them, you will be more likely to select consumers who are willing to buy the house you have on offer; and its all because you studied their interests, lifestyle and activities.

Market segmentation is a great way to analyse current and potential audiences. What are your thoughts? Let us know in the comments section below.
