RICHMOND, Texas — Deputies are investigating a deadly shooting in Richmond where they say a woman was shot and killed Monday during an argument with her boyfriend.

Santana Ray Lasoya, 23, has been charged with murder and booked into the Fort Bend County Jail.

This happened around 2:41 p.m. in the 6900 block of Pleak Crossing.

Detectives Williams with the Fort Bend County Sheriff's Office said Lasoya and 22-year-old Brandy Cano got physical during an argument. Lasoya told investigators that he picked up a gun and tried to leave, but Cano wouldn't let him.

The gun then went off, striking Cano in the head.

They have a 3-year-old child together who was not at the home during the shooting.

“Here is someone now that is going to have to raise that small child,” Sheriff Troy Nehls said during a media briefing.

Deputies said they have not been called to their home before.
