For the second time in a week, possible human remains have been found in Fairfax County.
A man walking his dog Thursday found some bones in the Manchester Lakes area.
Last Sunday, human remains were found alongside a nature path in Herndon.
The remains discovered on Thursday have not been positively identified as human, but investigators say they appear that way.
Fairfax County police say the man found the bones in the woods behind townhouse in the 6700 block of Zohra Court.
They were collected by the medical examiner who is attempting an identification.
The first set of remains last Sunday were found by a Herndon resident who was walking along a nature trail which is part of Difficult Run Stream Valley Park.
"At this point, there is no evidence linking the two sets of bones that have been found in Fairfax County this week," said Fairfax County Police spokesperson Lucy Caldwell. "It is unusual to have something like this happen twice in one week, but it is a large county with a lot of people here and police are working very closely with the Office of the Medical Examiner to determine exactly what happened."
It is unclear how long the bones were at each location, which is about 20 miles apart.
Earlier this week, police said there were no obvious signs of criminal activity in the bones that have been positively identified as human.
