Sean Michael Sullivan, 32, was wanted in connection with the Nov. 4 homicide in the 7800 block of Outlook Avenue in Oakland, according to the U.S. Marshals Service.
On that evening in November, Sullivan was arguing over an outstanding debt when he took out a firearm and shot two men, paralyzing one from the waist down and killing the other, according to the marshals service.
Prior to the altercation, Sullivan had a federal warrant for his arrest for violating a supervised release from a drug conviction that had a seven-year sentence, officials said. With the help of Oakland police, federal authorities found Sullivan on Thursday in a marijuana grow house in Oakland and arrested him, according to the marshals service.
