A man shot Wednesday by a Fairfield police officer had been reaching for a handgun in his waistband when the officer opened fire, officials said Thursday.

Christian Reyes, 22, of Fairfield, remains in critical condition at NorthBay Medical Center in Fairfield.

Events unfolded around 3:40 p.m. as a Solano sheriff’s deputy and Fairfield police Detective Robert Murray, both assigned to the Solano County Special Enforcement Team, were on patrol on Crowley Lane when they saw Reyes, who they believed had an outstanding warrant.

They attempted a stop, Fairfield officials said, but he ran off and a brief foot chase ensued.

At some point, Murray reportedly saw Reyes reaching for his gun. He fired multiple times, striking Reyes in the upper body, police said, and a replica firearm was recovered from his waistband.

Officials with the Solano County Sheriff’s Office, Fairfield Police Department and Solano County District Attorney’s Office flooded the scene soon after.

Officials closed Pennsylvania Avenue between Delaware and Texas streets, and Crowley Lane, to traffic.

Fairfield police are seeking witnesses to this incident.

Anyone with information is asked to call the Fairfield Police Department at 428-7300.
