Michael Brown

Michael Alexander Brown, a former marine who is suspected of killing his mother’s boyfriend, has been placed on theFBI’s most wanted list.

The United States District Court for the Western District of Virginia issued afederal arrest warrantfor Michael on November 13 after he was charged with unlawful flight to avoid prosecution.

Michael is described as a 22-year-old white male with brown hair and blue eyes who is 6 feet tall and weighs 145 pounds.

He was spotted in Franklin County on the day of the murder in surveillance footage at a local store, the Franklin County Sheriff’s Office said in anews releaseon November 10. He has been seen driving a white Cadillac, a black Lincoln town car and most recently, an RV pulling an enclosed trailer.

The sheriff’s office said that “it is currently unclear why Michael would have killed Rodney.”

Michael served as a combat engineer at Camp Lejeune in North Carolina, the sheriff’s office said, but deserted his post around October 18.

“It is unknown where Michael may be headed or where he has been staying since leaving his post,” the sheriff’s office said in its November 10 release. “He has been known to live in the woods and frequent National Parks and National Forest. He is believed to be armed with a high-powered rifle and may have access to other weapons.”

On November 12, investigators found the Lincoln town car Michael had previously been driving inside an enclosed trailer abandoned on the side of the road in Clarendon County, Virginia. Two days later, officers found the RV in Roanoke, which is where the search has since been focused.

The Franklin County Sheriff’s office did not immediately respond to PEOPLE’s request for comment Monday.
