MINNEAPOLIS - The Hennepin County Attorney's Office continues its war on drug dealers, filing murder charges against a man who allegedly sold a fatal dose of heroin.

Anthony West, 43, was charged with third-degree murder in the heroin overdose death of one of the people who received heroin from him. He also was charged with first-degree sale of heroin in the criminal complaint filed late Friday afternoon. Bail was set at $500,000 when West made his first court appearance Monday.

The criminal complaint filed against West states that on the morning of Feb. 25, 2017, police went to an Edina home and found a 27-year-old man dead at the desk in his bedroom. The medical examiner determined he died from fentanyl toxicity. Fentanyl is a powerful narcotic that is increasingly mixed into heroin, a practice that can bring deadly results.

A friend of the victim told police that the two of them went looking for heroin the evening of Feb. 24 and called West, her regular dealer. She and the victim bought heroin and immediately injected themselves with the drug. The woman says they parted company about 11:30 p.m., and cell phone records indicate the victim went back to his Edina home and did not leave.

During the investigation, police learned that West was routinely bringing heroin into Minnesota from Chicago. On Thursday, police officers pulled him over on Interstate 94 in Hennepin County, according to the complaint. They found nearly 30 grams of heroin in his underwear.
