The scene unfolded after 911 dispatchers received a phone call just before midnight Friday from a man who said "I killed my wife" and hung up the phone. He was never to be heard from again.
That man was later identified as retired Houston firefighter and paramedic Eugene Scott.
Police immediately responded to Scott's home on Glenheath near Ruthby. SWAT officers were called in when nobody answered the door.
After a standoff that lasted about two hours, officials sent in a robot camera and were able to see two bodies in the master bedroom.
Officers entered the home and found Scott and his wife, Sheila, dead. Police say it appears Scott killed his wife and then himself.
Police found a loaded gun in the home, but they can't confirm whether that is how both people died.
Ruy Lozano, a spokesperson for the Houston Fire Department, said Scott was a retired firefighter who was well-known in the community. He was with HFD for more than 20 years.
"[He was] promoted to the rank of captain, he was a paramedic, he served his community well and he's going to be missed," he said.
Lozano said the deaths have been especially hard on fellow firefighters.
"His fraternal family within the Houston Fire Department, his immediate family, the community that he lived with is grieving," Lozano said.
The Scotts are survived by three daughters.
