Police identified the victim as Carla Marizol Carias.
Detectives say Carias was not an intended target but was shot once by one of the burglars in a getaway car.
She was visiting her boyfriend who lives at the complex with his father.
Police say it was around midnight early Wednesday when the father and son heard someone breaking into Carias' car.
They went outside to see what was going on and that's when the two burglars got in their car and took off.
As they were driving away, investigators say one of them leaned out a window and fired one shot at the father, son and son's girlfriend.
The shot hit Carias, and she was rushed to the hospital where she was pronounced dead.
Carias' mother, Yolanda Avilez, said Carias' boyfriend called her at 1:30 a.m. and told her Carias had been taken to Memorial Hermann Hospital's emergency room. Avilez said she and her husband were brought into a room, and doctors told her Carias passed away because a bullet struck her in the largest vein in her heart.
"She's really nice, she's really kind and she's a really good person," said Yarany Medana, Carias' friend and the boyfriend's cousin.
Avilez said her daughter is dead all because criminals wanted to steal her car. She said Carias worked two jobs to buy the car she wanted. Avilez said she wants justice and the killers caught.
"We are still in the process of trying to gather as much info as possible. This is definitely a senseless homicide and we want to try and get the suspects as soon as possible," said Detective Mandy Arroyo, Houston Police Department.
Police don't have a good description of the two car burglars other than they are black males and they were in a dark-colored, four-door sedan.
Investigators believe it's likely they've been in the neighborhood before. There have been several car burglaries in that area recently.
