DNA tests have determined two sets of remains found in Fairfax County over the last two years belonged to brothers who went missing from Prince William County in 2010, police said Thursday.

Virginia’s medical examiner had previously determined the cause of death in both cases was murder, since both sets of remains showed blunt force trauma to the upper body, Fairfax County police said.

Manuel Mireles-Garcia and Alberto de Jesus Mireles-Garcia were last seen by family members around 10 p.m. on May 10, 2010 in the Triangle area, according to Prince William County police. Both were in their early 30s when they went missing.

Family members reported their disappearance two days later.

The brothers’ vehicles were located at their Triangle residence, but their IDs and keys were gone, police said. A search of the brothers’ shared apartment turned up no additional clues to their whereabouts, police said.

Manuel’s skeletal remains were discovered just off the roadway in the 10200 block of Furnace Road in the Lorton area on July 12, 2010, police said. He was wearing a chain necklace with a stone, heart pendant and an “evil eye” talisman attached, police said.

He also had on a green, American Eagle brand track suit, Cherokee brand pajama pants , a blue colored t-shirt with a picture of a hot road and a pair of white Reebok sneakers, according to police.

Alberto’s skeletal remains was discovered about a mile or two away on Furnace Road on March 15, 2011, police said. They were found at the base of a railroad trestle bridge by a man walking between Richmond Highway and Old Colchester Road, police said.

Police released no other details about the case.

“They weren’t found too far apart from each other, but it wasn’t exactly close,” said Eddy Azcarate, a spokesman for the Fairfax County police. “We don’t know when they died or where. It’s all still under investigation.”
