UPDATE: Bryan Glenn Found Dead in Thaiss Park

Update 9:09 p.m.: The Glenn family has released a statement confirming that the body found today in Thaiss Park is that of Bryan Glenn, a Woodson High School senior who had been missing since last Monday. 

Update 4:16 p.m.: Fairfax County police said Monday afternoon a male body was discovered Monday about three-fourths of a mile past the tree line at Thaiss Park.

Speaking not far from that tree line, Officer Eddy Azcarate said the search party organized by Bryan Glenn's family — not police — discovered the body today.

Azcarate told members of the media gathered at the scene that police could have missed the body in their search last week for a number of reasons: the initial search was not the step-by-step, grid sweep most residents think of when they hear about a police search, he said. The body was found near one of the park's paths, but not on it, Azcarate said — it's possible officers did not search far enough from the location of Glenn's parked car on Pickett Road, or, it could have been a gap in the search process.

The body was only just visible from a foot path when volunteers discovered it Monday, Azcarate said.

Autopsy results will not be available until Tuesday afternoon, Azcarate said.

Azcarate was not willing to comment on the condition of the body, nor whether weapons or valuables were found nearby.

Update: Thaiss Park near Pickett Road is completely blocked off to the public.

Fairfax County police and several media trucks are on scene.

Patch will continue to update this story as it develops.

Original: Just more than a week after Bryan Glenn went missing after dropping his younger brother off at school, a male was found dead Monday near Glenn's car in Thaiss Park.

Police had recovered the 17-year-old's car at the park Oct. 2, but volunteers did not discover the body until after 10:30 a.m., when they gathered wearing waterproof boots, long pants and clothing with vibrant colors to search for the varsity football player.

It is not clear where exactly in the park the body was found, and police have not positively identified the body as that of the missing teen. 

However, condolences and prayers for Glenn and his family began pouring in just after 2 p.m. on a Facebook page named "Find Bryan Glenn," which as of this afternoon had 2,748 members.

"My thoughts and prayers have been with the family through this ordeal, and even more so now with this heartbreaking news," one member wrote.

There is no cause of death available at this time.

Patch will update this story as more information becomes available.
