A Texas man shot and killed his girlfriend before killing himself after a fight erupted over sharing a $500 winning scratch-off lottery ticket, according to a report.

Terry Martin, 46, shot his girlfriend, Laurice Hampton, 48, at a Fort Worth home over the weekend and then turned the gun on himself, police told the Fort Worth Star Telegram. Martin was found dead with a gunshot wound to the head. Hampton was able to dial 911 but later died at a local hospital.

“The suspect didn’t want to share [the lottery ticket] with her,” Fort Worth police officer Joe Loughman said of Martin.

Martin had previously served jail time for assaulting Hampton, according to the Star Telegram.
