The Riverside County Sheriff's Department identified the man Sunday as John Felix.
Officials say he surrendered after a lengthy standoff. He was injured and treated at a hospital.
Palm Springs Police Chief Bryan Reyes identified the officers slain Saturday as Jose "Gil" Gilbert Vega and Lesley Zerebny.
Twenty-seven-year-old Zerebny had been with the department for about 18 months and recently returned from maternity leave after giving birth to a daughter. Vega was a 35-year veteran who planned to retire in December.
The wounded officer's name was not released.
