Garland police said a man shot his wife, drove her to the hospital and then turned the gun on himself Tuesday night.
Police said David Espinosa, 32, and his wife, Ana Porto, 29, were arguing outside of a Starbucks near Arapaho and Shiloh roads at about 7:20 p.m. Tuesday night when witnesses saw him grab her and force her into a pickup truck. He then pointed a gun at her, shot her in the chest one time and drove off.
Police began searching for the couple and alerted area hospitals of the reported shooting.
At about 7:45 p.m., the man's pickup truck pulled up to the emergency unloading area at Medical City Hospital in Dallas, and the woman made her way into the emergency room, police said.
A Dallas police officer working at the hospital went outside to the pickup and said he found Espinosa in the driver's seat with an apparent self-inflicted gunshot wound to the head.
The man was taken into the emergency room, where he was pronounced dead.
Porto was transported to Medical Center of Plano, where she was in stable condition, hospital officials said.
Neighbors said Wednesday they were shocked by the shootings.
"I just broke down and cried, because it's just such a tragic, senseless crime," Juanita Baldwin said.
Neighbors said the couple moved to the neighborhood about five years ago and were separating.
"My heart goes out to the them -- the kids," said Reginald Davis, who lived next door to the couple. "I'll be praying for them at night, and so will the rest of my family. I'm sorry that happened."
