The Mondawmin Safe Streets director was quoted saying Barksdale "had a large impact on reducing violence in our targeted area." Police say an informant told them last month that Mullen was dealing drugs, and on December 7 plain-clothes detectives stopped his truck, allegedly because they say he was not wearing a seat belt. Mullen allegedly moved "furtively" before rolling down his window to give up his license and registration. He told police he was working for Safe Streets but declined to give them permission to search the truck for guns and drugs. They called for the dog, observed Mullen allegedly put his hands down his pants, and pulled him from his truck for a pat-down. The gun was in the waistband, according to the incident report police emailed to reporters. Mullen's driver's license was suspended this year, according to online court records, when he failed to appear for a July seat belt infraction. He was charged with assault in late 2011 (the charges dropped), and with possessing a contraband cell phone while in prison in 2008. He was serving time for murder—30 years, with 22 suspended—starting in 2005. Mullens had previously been sentenced to five years for illegal possession of a gun, in 2004. It is unclear from the available record how he happened to serve five years, get released, kill someone, and be sentenced again during that year.
