A Baltimore City schools police officer pleaded guilty Monday to drug conspiracy charges in U.S. District Court, and faces no less than five years in prison.

Napoleon McLain Jr., 31, a four-year veteran whose father was a longtime Baltimore Police homicide detective, pleaded guilty to conspiring to distribute crack cocaine and drug possession with intent to distribute cocaine base. According to his plea agreement, McLain sold cocaine to a confidential source, who was working with authorities, on four occasions between December 2012 and August 2013.

McLain admitted purchasing "multiple ounces of cocaine base at a time from his suppliers," and selling 150 grams of crack to the informant for a total of $9,800, according to a statement of facts read in court.

U.S. District Judge Catherine C. Blake told McLain that he faces a mandatory minimum of five years in prison. The maximum sentence is 40 years.

The charges against McLain were made public for the first time last week, though his plea agreement was drafted in April. Three FBI agents attended the hearing, according to Assistant U.S. Attorney David Sharfstein. FBI investigators believe the drug dealing was limited to McLain, agency spokeswoman Amy J. Thoreson said.

"We haven't developed any information that other officers were involved," Thoreson said in a statement.

McLain's attorney, James Crawford, said his client "no longer works" for city schools police as of Monday morning. School district officials confirmed on Monday that he had resigned. District officials said McLain began working for city schools in February 2009. They declined to comment further.

Crawford noted that McLain has a side business running a long-term care home, called Delicate Hands Home Care, in Reisterstown.

McLain, who lives in Randallstown, is scheduled to be sentenced on Oct. 15, federal prosecutors said.
