Police believe a Garland man may have killed his wife, daughter and the family dog and then took his own life, although an investigation was continuing on Wednesday.
The discovery was made at about 9:45 a.m. Tuesday at an apartment complex in the 2100 block of West Campbell Road, said Officer Joe Harn, police spokesman.
Co-workers of Robert Andrews, 46, got concerned when he didn't show up for work, so they called the apartment managers to check on him.
"When management went inside they saw a body, backed out of the apartment and called police," Harn said. "When police arrived they discovered three bodies inside, two females and a male."

The preliminary investigation indicated that Andrews fatally shot his wife, Tammy Andrews, 46, daughter Sarah, 17, and the dog, and then shot himself, Harn said.
The pet was described as a full-size mixed-breed dog, possibly part Labrador retriever, Harn said.
"Police did recover a pistol they believe to be the murder weapon," Harn said. The gun, he added, was found near the body of Robert Andrews.
Police were awaiting a ruling from the Dallas County medical examiner's office to confirm whether Andrews killed himself, Harn said.
"While waiting for that ruling, detectives will continue to contact neighbors, co-workers and anyone else who may give some reasoning for why this happened," Harn said.
