An Odessa man is behind bars, and facing federal drug charges.
Sheriff's Office investigators have confiscated about 40-thousand dollars worth of black tar heroin.
20-year old Michael Villa was arrested Monday afternoon in the 700 block of North Muskingum.
Deputies say they pulled over Villa and a juvenile passenger after a week-long investigation, and after getting permission to search the car, they say they found almost 230 grams of black tar heroin packaged to sell.
They also discovered a small amount of marijuana.
Villa is now in the Ector County Detention Center awaiting formal federal charges.
