An infant's cries led a southwest Houston woman to her neighbor's apartment, where she found the baby girl's parents shot to death, officials said.
Police said a woman who was walking her dog about 6:30 p.m. Wednesday heard a child crying in the apartment, then found the couple.
Two men were seen fleeing from the area after the shooting, police said. Thursday afternoon, police released composite sketches of the two men.
One is about 18 to 20 years old, about 5 feet 11 inches tall, has a baby-face appearance and hair cut in a distinctive round afro. He was wearing a pink or orange T-shirt.
The other is about 17 to 20, about 5 feet 9 inches tall, with his hair done in twisted curls. He was last seen in a white T-shirt.
Investigators did not release other information, including if a gun was found at the scene.
Olguin said the child was placed with a foster family when the agency took emergency custody of the baby Wednesday night.
The agency is attempting to find out the child's name as well as the names of her other relatives, if she has any.
If the child's relatives are found and they are suitable to care for her, the baby could be placed with them.
