An Ypsilanti man investigators say ran a drug house where an off-duty University of Michigan police officer was spotted hours before he was arrested with cocaine in January was indicted Monday on federal gun and drug charges, court records show.

Derreck Davison, 50, is charged with possession with intent to distribute cocaine, possession with intent to distribute marijuana, maintaining a drug premises, being a felon in possession of a firearm and possession of a firearm in furtherance of a drug trafficking crime.

Davison is not in custody, said ATF Special Agent Donald Dawkins, a bureau spokesman in Detroit. Dawkins declined to comment on the case, citing an ongoing investigation in conjunction with the Livingston and Washtenaw Narcotics Enforcement Team.

The indictment alleges that Davison maintained a drug house on East Ainsworth Street in Ypsilanti on Jan. 15 to sell cocaine and marijuana. On that date, he is accused of possessing three rifles, two pistols, a shotgun and revolver, the indictment says.

Investigators were familiar with Davison's home, LAWNET records show. Two days earlier, LAWNET investigators followed off-duty University of Michigan police officer Charles Eugene Beatty III there as they were conducting surveillance on Beatty, records show. They were following up on information including that Beatty had allegedly purchased cocaine at the home in the past, reports say.

Investigators had been tracking Beatty for more than a month after attaching a GPS unit to his car, records show. Officers saw Beatty at the home and arrested him hours later during a traffic stop, when they recovered less than a gram of cocaine, reports say.

Beatty was put on unpaid leave the day after the incident, his employment ended weeks later and he ultimately pleaded guilty to possessing less than 25 grams of cocaine. He was sentenced to probation. On the night of his arrest, Beatty declined to give a statement to state police, records show.

According to Washtenaw County court records, Davison has lived at the home for at least 14 years. He has convictions for possessing less than 25 grams of cocaine, use of cocaine, operating while under the influence of liquor and possession of marijuana, records show.

Davison could not be reached for comment today.
