A New York man who was allegedly fighting with his wife ended up shooting her dead, as well as his own father and grandmother, years after his mom claims she predicted he was “going to kill somebody someday,” according to cops and reports.

Joshua Fowler, 26, is accused of murdering his wife, Whitney Fowler, his father, Wilson Fowler, and his grandmother, Anita Crandall, on Wednesday night. The Fowlers and Crandall lived together at a home in Grafton, roughly 40 miles west of Boston, according to local CBS affiliate WRGB.

Joshua Fowler’s mother, Eleanor Crandall, told the outlet he has mental health problems and has allegedly refused to get help.

“To me, my son died that night, too,” Crandall said.

“I hate him,” she added. “And that’s a very strong word in my vocabulary. I don’t use that word unless I have to.”

Police reportedly went to the Fowler residence multiple times in the past in response to domestic disturbance calls before the triple homicide last week. Joshua Fowler’s mom says he has dealt with anger and mental health issues for years, to the point where she thought he was going to hurt someone.

“I told his father when he was 15 years old, ‘You need to get him mental help because he’s going to kill somebody someday,'” Crandall told WRGB.
