Sacramento police are investigating a deadly home invasion robbery early Saturday in which one of the intruders was shot dead and three other people were wounded.

The identities of all but one person in the shooting were withheld pending the results of a preliminary investigation, according to police spokesman Officer Doug Morse.

Police identified one alleged intruder as Thomas Ordonaz, 21. Ordonaz was arrested Saturday night for investigation of assault with a deadly weapon and being an accessory.

Morse said that at 3:29 a.m. officers responded to reports of shots fired on Haven Court off Greenhaven Drive in the Pocket neighborhood of Sacramento.

Upon arrival, Morse said, officers quickly discovered that an exchange of gunfire had occurred between the homeowner and would-be robbers.

One of the intruders was fatally wounded and pronounced dead at the scene by Sacramento Fire Department personnel, Morse said. Three others, including the homeowner, were shot during the exchange of gunfire and suffered non-life-threatening injuries. The three were transported to a hospital for treatment.

Sacramento Police Department homicide detectives and crime scene analysts are investigating the circumstances that led to the shootout, Morse said..

"There were some juveniles in the home who didn't live there, but they were not involved in the shooting and were not injured," he said. It appears there was a sleepover, he added.

The Sacramento Police Department urges anyone with information about the crime to call the dispatch center at (916) 264-5471 or Crime Alert at (916) 443-4357.
