Houston police reported finding a 66-year-old man lying in the street at 15700 Baybriar Drive with multiple gunshot wounds.
He was transported to the hospital where he later died Saturday morning.
An investigation revealed that before the shooting, the man was involved in a verbal argument with a neighbor.
The neighbor has only been identified as a 75-year-old woman.
She was initially arrested for aggravated assault, but murder charges are pending after the man's passing.
