Yatee Her was arrested Friday night by members of the multi-agency gang enforcement consortium or MAGEC.
The 31-year-old was wanted for killing one person and injuring two others during a shooting in Oroville on Nov. 26.
Authorities say a video surveillance system showed him sitting in his wheelchair and firing at the victim, who was just a few feet away.
Detectives tracked Her down to a home on Roy Avenue. They also arrested another man on accessory charges and three people for harboring and gang enhancements.
On Saturday, MAGEC found several guns, including a banned assault rifle, while searching a home on Byrd Avenue where Her was staying. They arrested his brother-in-law on several weapons violations.
