A newborn who was abducted from his dying mother after she was repeatedly shot outside a US paediatric centre was found safe hours later, according to Texan investigators who said the suspected killer sped off with the infant in a blood-stained Lexus.
The three-day-old boy named Keegan was found about 8pm local time on Tuesday, about six hours after his mother, Kala Marie Golden, was fatally shot following a verbal altercation in a suburban Houston parking lot, Montgomery County District Attorney Brett Ligon said.
Mr Ligon would not say where the infant was found, but he said it was not at a nearby apartment complex where officers wielding guns and riot shields searched earlier on Tuesday evening.
"The child is healthy. The father of the child is on his way to be reunited with the child," Mr Ligon told The Associated Press.
A person of interest has been detained though no charges have been filed, he said. He would not provide any details about the person.
Ms Golden was leaving an afternoon check-up with Keegan when she had an argument with a woman in a Lexus parked next to her pick-up truck, Montgomery County sheriff's Lieutenant Dan Norris said.
Witnesses said the woman repeatedly shot Ms Golden, took the infant and sped away, hitting the dying mother as she screamed "my baby" and tried to reach into the Lexus, Lieutenant Norris said.
Witnesses also reported hearing as many as seven gunshots and said a man was also in the sky blue or light green Lexus, which was blood-stained on the driver's side, Lieutenant Norris said.
Investigators were processing evidence on Tuesday night at one apartment in the complex that was searched, and they took away a vehicle parked in front.
The shooting happened just after 2pm outside the Northwoods Paediatric Centre in Spring, which is about 35 kilometres north of Houston.
A handful of people sitting outside Ms Golden's nearby home said they were relatives, but declined to give their names. They said the family was grieving and would have no comment.
Joshua Jesson said he was in the clinic with his girlfriend when he heard gunshots. He said he saw a Lexus next to the pick-up truck, then later looked back and saw the car was gone and a woman lying in the spot where the Lexus had been parked.

"I thought she just passed out. Then somebody ran in here and said, 'Somebody got shot,'" he said.
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 pair of brown sandals near a red pick-up truck. Spent ammunition was also nearby.
The clinic is in an area thick with strip malls.
