A Texas father killed his wife and daughter before turning the gun on himself, PEOPLE confirms.

Jefferson Stovall, 46, was found dead Thursday in his Corsicana home near the bodies of his wife, Penny Stovall, 43, and 8-year-old daughter, MaKenzie, according to a Navarro County Sheriff’s news release.

Deputies checked on the family after receiving a call from worried family members, who said they hadn’t been able to reach the couple in 24 hours.

A .44 magnum rifle was found at the scene, according to the news release. Deputies gave no information on a possible motive.

Sheriff Elmer Tanner tells PEOPLE it was “blatantly obvious” that Jefferson was responsible for the killings, but he wouldn’t elaborate on why investigators believe this.

Tanner says police had never received reports of criminal incidents or family violence from the Stovall house.

He says there was “a presence of alcohol at the scene,” but says investigators are not sure if that was a contributing factor.

“Any time you’re dealing with the needless loss of life, especially a child of 8 years of age, innocent 8-year-old, it’s a traumatic experience for the community,” Tanner says. “But it’s also that we keep our officers in your thoughts and prayers, because it’s troubling for the officers to investigate such a scene.”

Tanner says he hopes the investigation will help “make sense of this senseless crime.”
