The nine children of a woman killed by her police officer ex-husband filed a wrongful death lawsuit against the department where he worked, as well as against several other law enforcement agencies.

The suit claims that the agencies failed to properly discipline Neptune Township Sgt. Philip Seidle and didn't properly report and investigate domestic violence incidents at the family's home, among other claims. It seeks undisclosed compensatory and punitive damages.

Seidle was off-duty when he shot and killed his ex-wife Tamara Wilson-Seidle with his service weapon after a car chase in June 2015. Their 7-year-old daughter was in the car at the time of the shooting.

Seidle pleaded guilty to aggravated manslaughter and child endangerment. He was sentenced last September to 30 years in prison.
