CHRISTIANSBURG -- A Christiansburg man who is charged with voluntary manslaughter in the death of his cousin was granted bond Friday and ordered not to have any contact with several witnesses in the case.

Keith Dean Quesenberry, 21, was charged after a medical examiner found that his cousin, Michael Andrew Quesenberry, died of injuries he suffered in an altercation.

The pair had been in a struggle before Michael Quesenberry was found unresponsive early the morning of Sept. 5, Christiansburg police said.

Quesenberry, 23, of Pearisburg died later that morning at Carilion New River Valley Medical Center.

A witness saw Keith Quesenberry with his arm around Michael Quesenberry's throat as the two struggled on the ground outside a home on Moose Drive, according to a search warrant affidavit filed in Montgomery County Circuit Court.

It was revealed at a bond hearing Friday in Montgomery County General District Court that Keith Quesenberry's brother pulled him off Michael Quesenberry and administered CPR.

The case has created tensions between the families.

Before Keith Quesenberry's hearing, a Montgomery County deputy announced to more than two dozen people in the courtroom that outbursts would not be tolerated. He said he understood there had been at least two incidents between the families since Michael Quesenberry's death.

Several people quietly cried during the hearing, but no one spoke, and the families were escorted out of the courtroom separately.

Keith Quesenberry testified that he returned to his mother's home in Christiansburg in July after serving with the U.S. Marines in Iraq. His wife and two young daughters also live there.

He stood with his head hung low as his mother, Donna Sutphin, clutched a Bible and spoke. She said her son, whom she described as a good father to his children, could return to her home if he were to be released from the Western Virginia Regional Jail.

His attorney, Jimmy Turk, said he doesn't believe there is any evidence that Keith Quesenberry intentionally killed his cousin. He said that alcohol was involved in the incident.

"Certainly it's a very tragic set of circumstances," he said. "It's very difficult on both of these two families."

General District Court Judge Randal Duncan set bond at $25,000 but also set several conditions.

He told Keith Quesenberry he cannot drink alcohol or use illegal drugs and he will be subject to random drug and alcohol screenings. He cannot leave the state and will be under house arrest at his mother's house from 8 p.m. to 6 a.m. every day. He also cannot have contact with witnesses, including Michael Quesenberry's parents or fiancee.
