Officer A. Alvarez, 28, was released on Monday and is recovering at home, HPD tweeted.
Alvarez was the most seriously injured when, according to police, Rolando Caballero opened fire on the three officers last Thursday, HPD said. Officers N. Gadson, 35, and D. Hayden, 32, were released from the hospital on Friday.
Caballero, 31, is charged with three counts of attempted capital murder of a police officer and one count of aggravated robbery.
HPD said the officers were responding to a possible domestic disturbance on the northeast side when Caballero led them on a chase. He crashed at the intersection of McGowen and Hutchins Street and that's when the shooting began.
When the officers got out of their vehicles, Caballero opened fire with a fully automatic weapon and ran off on foot, according to Police Chief Troy Finner.
Realizing the officers had been hit, a patrol officer picked them up in her vehicle and rushed them to the hospital.
Shots fired during SWAT standoff
Finner said Caballero carjacked a white Mercedes and got away again. He holed up at a home on Lockwood, where he fired more shots during an hours-long standoff, according to Finner. No other officers were hurt, but Caballero was wounded at some point.
After nearly five hours, he finally surrendered and was taken to the hospital for a bullet wound to the neck.
Caballero is accused of robbing a Katy auto shop at gunpoint in late December, according to records.
He also faces federal charges, including possession of a machine gun and felon in possession of a firearm.
A witness told police Caballero pointed a Glock with a gun switch at him before the chase.
According to ATF Special Agent in Charge Fred Milanowski, the gun switches allow a weapon to fire up to 30 rounds in as little as two seconds. He said the fully automatic switches have become more prevalent in Houston recently.
