Authorities say a suspect wanted in connection with a killing in Tucson has been arrested in California.
Tucson police say 24-year-old Zane Grey Williams was taken into custody Monday by a U.S. Marshals fugitive task force in San Diego.
They say Williams has been booked into a San Diego jail while he awaits extradition.
Police believe Williams and 23-year-old Javier Johansen were involved in a fight at a party at a Tucson apartment on March 23.
Authorities are withholding details on how Johansen was killed for investigative reasons.
Johansen's body was found in the apartment four days later after police received a phone call from a person with information about the killing.
On April 3, Tucson police obtained an arrest warrant for Williams on suspicion of first-degree murder.
