ROANOKE, Va. – An attorney who could represent a U.S. Marine deserter wanted for questioning in a murder case is again asking for the man to surrender peacefully.

Deborah Caldwell-Bono has agreed to represent 22-year-old Michael Alexander Brown and is asking that he turn himself in to law enforcement officers. Brown’s mother and grandmother issued a similar appeal over the weekend.

Caldwell-Bono says she doesn’t know where Brown is and hasn’t spoken to him but pointed out that he has harmed no one since the murder. She says she has talked to some of Brown’s friends, who asked her to represent him.

Brown’s mother, Vanessa Hanson, stated in a criminal complaint that she witnessed her son fatally shoot her boyfriend, Rodney Wilfred Brown, earlier this month at a home in Hardy, Va.

Roanoke police chief Tim Jones says investigators believe Brown was sighted trying to contact his mother and grandmother Thursday. He had deserted his post at Camp Lejeune in North Carolina last month.
