Acting on a tip, Medford police responded to a residence on Court Street Wednesday and made contact with three subjects, who are all convicted felons. Investigators located a fully automatic machine gun inside the residence. The investigation led police to a trailer park in Talent, where the Medford SWAT Team, with assistance from Talent PD, served a search warrant at a trailer inside the park. Eight firearms were recovered, as well as a bullet proof vest and drug paraphernalia.
