A 31-year-old man alleged to be one of Minnesota's biggest heroin dealers has been charged with third-degree murder and two counts involving drug crimes.

Jaime Edward McClellan, who lists addresses in both Maple Grove and Brooklyn Park, was charged Monday in Hennepin County District Court with third-degree murder in connection with a fatal heroin overdose.

He also was charged Friday in Anoka County District Court with first-degree intent to sell a controlled substance and second-degree possession of a controlled substance.

He was being held Monday in the Anoka County jail, where bail was set at $1 million. McClellan has prior second- and third-degree controlled substance convictions in Ramsey County District Court.

According to the complaint filed in Hennepin County, officers on Oct. 24 found a man who had overdosed on heroin in his Medina home. After getting a search warrant, they seized the victim's two computers and a cellphone from which they learned that McClellan was his supplier.

They also discovered that McClellan was a suspect in an ongoing Anoka County death investigation in which another person had died from a heroin overdose.

According to the Anoka County complaint, the Anoka Hennepin Drug Task Force confiscated 20 grams of heroin and conducted several undercover purchases in Mounds View, Blaine, Brooklyn Park and Rogers from Nov. 12 to Dec. 16. During most of the purchases, a confidential informant bought the drugs from a person believed to be a relative of McClellan's.

On Dec. 16, drug task force detectives went to Minnesota Muscle, a gym in Mounds View, to arrest McClellan. He was sitting next to a pair of red boots that contained 15 grams of heroin of the type he allegedly sold during the controlled buys.

Officers also seized $349,130 from a storage locker in Plymouth.

"The state believes that the defendant is a major distributor of heroin," according to the Anoka County District Court criminal complaint.
