Around 9:50 p.m., officers responded to reports of a shooting at a gas station in Houston, Texas.
Upon arrival, they found a woman with a gunshot wound. She was pronounced dead at the scene.
The victim was identified as 24-year-old Sarah Taplin.
Investigators said the shooting escalated from a fight between the victim and another woman.
The victim’s brother, 35-year-old Richard Taplin, was allegedly present during the incident, grabbed a gun from someone nearby and fired at the person his sister was fighting with as the woman ran away.
Police said, Richard Taplin shot “indiscriminately into a crowded gas station parking lot” and struck his sister at least once, before fleeing.
Richard Taplin is charged with murder, aggravated assault with a deadly weapon and unlawful carry of a weapon with a felony conviction, according to police.
As of April 29, Taplin had not been caught. Authorities said Taplin should be considered armed and dangerous.
Officers are asking anyone with information to call the Houston Police Department Homicide Division at 713-308-3600 or Crime Stoppers at 713-222-8477.
