The teenager's body was found in a cemetery.
Local police tell Action News that all information in this particular investigation will come out of the Montgomery County District Attorney's Office in Norristown.
Authorities say the teenager climbed a ladder and then fell 175 feet from the top of a mausoleum tower in the Whitemarsh Memorial Park in Horsham.
Investigators worked into the night, after a 9-1-1 call was made around 2:36 Sunday afternoon concerning suspicious activity at the cemetery.
The prime focus for police appeared to be in the area adjacent to the park's signature structure, the 174-foot Tower of Chimes.
The deceased was a student at nearby Hatboro-Horsham High School. A Facebook memorial page has been set up where scores of online posts remember the teen as good-hearted, a joke teller. He was also described as a daredevil. One comment saying: "Literally, the most fearless kid I knew."
School officials have said counselors will be available for classmates troubled by the death.
Hatboro-Horsham School District Superintendent Curtis Griffin released a statement that said, in part: "I know I speak for the entire high school staff when I say that our sympathies go out to this teenager. We are committed to working together during this sad time to help the students of our high school handle this loss."
The investigation by the District Attorney's Office and by County Detectives continues. No word yet into the manner or cause in Sunday's death.
