SPRING, TEXAS - A newborn who was abducted from his dying mother after she was repeatedly shot outside a doctor's office in suburban Houston was found safe Tuesday night, investigators said.

The healthy 3-day-old infant was found about six hours after his mother was fatally shot following an argument in a parking lot, Montgomery County District Attorney Brett Ligon said. Ligon wouldn't say where the infant was found, but said that the baby was being reunited with his father.

A person of interest has been detained, although no charges have been filed, he said.

The boy's mother, Kayla Marie Golden, 28, was leaving an afternoon checkup with her son when she had a verbal altercation with a woman in a Lexus parked next to her pickup truck, Montgomery County sheriff's Lt. Dan Norris said.

Witnesses said that the woman repeatedly shot Golden, took the infant and sped away, hitting the dying mother as she screamed "My baby!" and tried to reach into the Lexus, Norris said. Witnesses also reported hearing as many as seven gunshots and said that a man also was in the Lexus, which is blood-stained on the driver's side, Norris said.

Officers searched a nearby apartment complex Tuesday night for the boy but did not find him, Deputy U.S. Marshal Alfredo Perez said. It wasn't immediately clear what led authorities to the complex, where officers were seen wielding guns and riot shields.

The shooting happened just after 2 p.m. outside the Northwoods Pediatric Center in Spring, which is about 20 miles north of Houston. A statewide emergency alert was issued for the baby.

Police quickly surrounded the clinic and much of the parking lot with crime-scene tape, and yellow markers were placed next to a purse and a pair of brown sandals near a red pickup truck. Spent ammunition also was nearby.
