A Michigan college student was fatally shot by her ex-boyfriend in what police are calling a murder-suicide, after months of stalking and harassment, as reported by The New York Post.

Sarah Carroll, 20, was killed Saturday at the Woodland Villa Apartments in Westland, near Detroit, according to Fox 2.

Police identified the incident as a murder-suicide after her ex-boyfriend, identified only as Lincoln, called 911 to report that he had shot Carroll before taking his own life.

Carroll’s mother, Jennifer Carroll, said her daughter had been attempting to obtain a personal protection order against Lincoln in the weeks before the shooting.

“She was with Lincoln, her ex-boyfriend, for almost a year and they were having trouble,” Jennifer told Fox 2. “He was stalking her for the past two months. And he came here last night, shot her, called 911, said he killed his girlfriend, and then shot himself.”

Jennifer added that her daughter had not told her parents about the extent of the stalking before the tragedy. “To other parents — watch your kids,” she told Click on Detroit. “Try to get more into their life, try to get them to be open and talk to you.”

Sarah’s father, James Carroll, said Lincoln “was suffering from mental illness” and that his daughter had been shot multiple times with a shotgun.

“If their children are suffering from mental illness, get them some help. Get them the help that they need before something like this happens,” he said.

Carroll was a student at Schoolcraft College, where she was pursuing a degree to become a physician assistant. Her father described her as someone who was loved by everyone who knew her. “She was wonderful. I’m going to miss my baby,” he said.

The Westland Police Department said it will release further details as the investigation continues.

A GoFundMe page created to help cover funeral expenses described Sarah as “smart, brave, strong, and with a smile that lit up every room she entered.”

The fundraiser’s organizer, Deborah Carroll, wrote, “She was only just beginning her journey, and losing her at such a young age is something no family should ever have to go through.”

James Carroll also posted on Facebook to thank supporters for their generosity. “We are truly overwhelmed by the outpouring of love, support, and generosity we have received through this GoFundMe,” he wrote.

“Every single donation, share, and prayer means more to us than words can express.”

Authorities said they will provide additional updates later this week.
