Four Baltimore residents are charged with multiple offenses in connection with a home invasion in Walkersville.

Deputies with the Frederick County Sheriff's Office arrested 48 year old Keith White, 20 year old Cheryl White, 19 year old Jesse Mears and 19 year old Diontre Johnson, after they were found inside of a townhouse in the 8400 block of Vision Lane early Sunday morning. Authorities said the suspects entered the residence, sometime Saturday night, duct taped a female's mouth and her hands behind her back, and then threatened the victim with a handgun and a knife. Hostage negotiators were held at bay for several hours. Investigators were able to conclude that the incident was related to the sale of illegal drugs.
