A Michigan man has been convicted of second-degree murder in the shooting death and mutilation of his childhood friend three years ago in a field north of Detroit.

A Macomb County jury on Thursday found 21-year-old Andrew Fiacco guilty in the killing of 19-year-old Stephen McAfee. The jury also found Fiacco guilty of a felony firearm offense, dismemberment and lying to a police officer.

Kristina Joseph, one of Fiacco's attorneys, said they were disappointed with the verdict and "do believe he used lawful self-defense."

His sentencing is set for March 21. He could face decades in prison.

Prosecutors say Fiacco shot McAfee twice in the head in a remote Bruce Township field in March 2016 then dismembered his body and buried some remains on family property.

McAfee's family reported him missing about three days after authorities believe he was killed.

Fiacco said nothing for a year, and twice told an investigator that he had no information on the location of his friend.

In April 2017, he showed investigators where they could find McAfee's remains, in two shallow graves about 10 miles (16 kilometers) apart.

Mark Morfino, Macomb County Sheriff's detective, told a district court in 2017 that Fiacco took his 20-year-old ex-girlfriend, Eevette MacDonald, to the vacant, privately owned field where McAfee was shot, to "show her something" about a month after McAfee was killed.

A female associate later told sheriff's deputies that MacDonald had told her Fiacco was responsible for McAfee's death.

MacDonald pleaded guilty in December to being an accessary and to exhumation and mutilation of a body. A third charge of lying to police is to be dismissed at sentencing, which is set for March 7.
