It is unclear how Melaku went from serving in the military to getting involved in the strange and disruptive event, but he has shown signs of trouble recently.
At the end of May, a man with the same name was arrested in connection with car vandalism incidents in Leesburg.
“The general consensus is that it might be some type of mental issue with the guy,” said a law enforcement source who spoke on condition of anonymity because the investigation is unfolding.
Melaku is a vehicle operator with the 4th Combat Engineer Battalion, based in Baltimore. He joined the Marine Corps Reserve in September 2007 but has never been deployed.
