DRAPER, Utah – Police released new information Friday about the 7-vehicle accident that killed one woman, seriously injured her daughter and caused lesser injuries to several other people Thursday night.
Susan Madsen, 43, of Draper died at the scene and her daughter was seriously injured in
the crash that occurred at the intersection of 12300 South and Lone Peak Parkway Thursday at about 6:30 p.m. Four other people were transported to hospitals with minor injuries.
According to a press release from the Draper City Police Department, the man who caused the crash is 44-year-old Bill Robert Thompson. Police stated they received a call about a domestic violence report, but the suspect left before police arrived.
A statement of probable cause states Thompson allegedly assaulted multiple people at that location before driving away.
The court document states Thompson was involved in an altercation with his roommate, and that Thompson hit the roommate several times in the face with an open hand—while the roommate was holding Thompson’s son.
Neighbors who reported they tried to help the roommate said Thompson also assaulted them. There were two children in the home who witnessed the altercation.
At about 6:30 p.m., a person reported that the white truck drove toward their vehicle while it was stopped and made contact with the vehicle. The victim stated the driver of the truck began laughing and staring the victim down before leaving.
The 7-car accident occurred a few minutes after the first collision, and officers later determined Thompson was the suspect in the domestic investigation.
Thompson was taken to a hospital for injuries he sustained in the crash. He was booked into jail after he was released.
According to the statement of probable cause, Thompson faces charges that include aggravated assault as a third-degree felony, automobile homicide as a second-degree felony, DUI with serious bodily injury as a third-degree felony, and seven counts of DUI with bodily injury as class A misdemeanors, domestic assault as a class B misdemeanor and two counts of domestic assault in the presence of a child.
