Milwaukee man sentenced after traffic accident that killed pregnant wife

A Milwaukee man is found guilty of killing a pregnant woman in a crash in Wauwatosa in 2023. Frank Mosley, 21, was convicted Wednesday of two counts of first-degree manslaughter, hit-and-run causing death and fleeing from police. Erin Mogensen, 33, and her unborn child were killed in the Nov. 2, 2023 crash at the corner of 100th Street and Capitol Drive. The devastating crash occurred just two blocks from Mogensen's home when Mosley ran a red light and sideswiped her car. Police video taken seconds before the crash showed the driver of the stolen BMW speeding away from Wauwatosa police at 116 mph five seconds before impact. Investigators determined the BMW was still traveling 61 mph when it crashed into Mogensen. “Most of us, including myself and probably all of you, have never driven 116 mph in a car, maybe in an airplane,” Assistant District Attorney Michael Lonski said in his closing argument Wednesday. During the three-day trial, prosecutors showed a video showing the driver of the stolen car fleeing the scene of the crash. Investigators also testified they found a Walmart receipt in the car and used surveillance video from the store to identify Mosley. Prosecutors said they also found Mosley's DNA on the airbag of the crashed BMW. The car's key fob was on a table in his home when police arrested him that same day, and in the backyard, police found BMW paperwork for that car burning in a backyard grill. “All of those things point to him because he's the guy who drove that BMW and killed Erin Mogensen and her unborn baby,” Lonski said. “And you should find him guilty.” In his plea, Mosley's defense attorney said he was being made a scapegoat for Milwaukee's reckless driving epidemic. “I'm sick of it. I live in this community, too. I drive on these roads. We have to do something about it,” said attorney Quron Payne. “But we can't let that frustration justify us pointing fingers at anyone.” Jurors took just three hours to return guilty verdicts on all counts. Payne was remanded in custody and will remain in custody until his sentencing is announced Nov. 21. Mogensen's father declined to comment after the verdict as the family left the courtroom in tears. They will have the opportunity to address the judge at Mosley's sentencing. The family successfully lobbied for a change in state law after Mogensen's death. A law the governor signed this year increases penalties for cases of reckless driving that result in serious injury or death, including mandatory jail time.

A Milwaukee man is found guilty of killing a pregnant woman in a traffic accident in Wauwatosa in 2023.

Frank Mosley, 21, was found guilty Wednesday of two counts of first-degree manslaughter, hit-and-run causing death and fleeing from police.

Erin Mogensen, 33, and her unborn child were killed in the accident on November 2, 2023, at the corner of 100th Street and Capitol Drive.

The devastating crash occurred just two blocks from Mogensen's home when Mosley ran a red light and sideswiped her car. Police video taken seconds before the crash showed the driver of the stolen BMW speeding away from Wauwatosa police at 116 mph five seconds before impact. Investigators determined the BMW was still traveling 61 mph when it crashed into Mogensen.

“Most of us, me and probably all of you, have never driven 116 miles per hour in a car, maybe in an airplane,” Assistant District Attorney Michael Lonski said in his closing argument Wednesday.

During the three-day trial, prosecutors showed video showing the driver of the stolen car fleeing the scene. Investigators also testified they found a Walmart receipt in the car and identified Mosley from store surveillance video.

In his plea, Mosley's defense attorney said he was being made a scapegoat for Milwaukee's reckless driving epidemic.

“I'm fed up. I live in this community too. I drive on these roads. We have to do something about it,” said attorney Quron Payne. “But we can't let that frustration give us the right to point fingers at anyone.”

The jury took just three hours to return guilty verdicts on all charges. Payne was remanded in custody and will remain in custody until his sentencing on November 21.

Mogensen's father declined to comment after the verdict, while the family left the courtroom in tears. They will have the opportunity to address the judge at Mosley's sentencing hearing.

After Mogensen's death, the family successfully lobbied for a change in state law. A law the governor signed this year increases penalties for cases of reckless driving that result in serious injury or death, including mandatory jail time.
