Arthur Raymond Uribe, 24, turned himself in to the San Bernardino Police station Monday morning, Lt. Rod Topping said.
On Jan. 4, Uribe allegedly barged into a mobile home in the 700 block of East Base Line and shot his former girlfriend and her new boyfriend, according to police officials.
The couple was taken to an undisclosed hospital with non-life threatening injuries. Their current conditions were unknown but they were expected to survive. Authorities also didn't comment if they had been released from the hospital.
It was unclear what led up to the shooting.
Court records show Uribe was previously arrested and convicted of felony vandalism in 2006, but outside of that has no serious criminal record. He is scheduled to be back in court on Jan. 18.
