SPRING -- A man made a horrific discovery late Friday night when he found his mother and grandmother dead. Harris County Sheriff’s investigators said it is likely both women were stabbed to death.

Officials said Theron Owens arrived at his mother’s residence in the 6600 block of Springfield Garden in northwest Harris County just before midnight when he found his mother Joyce Owens, 63, and his grandmother Alberta Walker dead.

The discovery sent chills through the neighborhood. Neighbors said the murder victims lived in the home after moving to the area after fleeing Hurricane Katrina. The son said one of the women was found stabbed to death in the kitchen while the other was found in a bedroom.

Investigators did not say they had any suspects, but Owens said he was handcuffed, taken into police custody for eight hours and questioned about the women’s deaths.

Owens accused investigators of singling him out because of his race and because he was the closest family member to the two women.

 “It’s pathetic, it’s sad. Basically, they aren’t looking for anybody else. Like (investigators) said, ‘You got two strikes against you. You are black and you are from New Orleans,’” Owens claimed he was told.

Investigators would not talk to 11 News about the investigation or why Owens was detained. But the man was not arrested.

Anyone with information on the homicides should call Crime Stoppers at (713) 222-8477.
