ROWLEY – Federal investigators are looking into the death of a worker from Salem, New Hampshire who died after falling from a tree in Rowley Thursday morning.

The Essex District Attorney's Office said 34-year-old David Bova was working on a crew from Mayer Tree Service of Essex at a private residence at 29 Main St., Rowley, mid-morning Thursday. 

Bova was in the tree preparing to remove a branch when he suddenly fell from about 50 feet up. He was taken to Anna Jacques Hospital where he was pronounced dead, the statement from the DA's Office said.  

While foul play is not suspected, the matter remains under investigation by the Essex State Police Detective Unit and the Rowley Police Department. 

In October 2010, Bova fell 40 or 50 feet from a pine tree and was airlifted to a Boston area hospital by medical helicopter. Bova was working on a 60-foot pine at 180 Jackson St., Methuen, when that accident occurred, according to Methuen police. 

The local office of the federal Occupational Safety and Health Administration was notified Thursday morning and has begun an inspection to determine whether Mayer Tree Service violated any safety standards at the Rowley work site. Such inspections can take no longer than six months, per OSHA regulations. And while many investigations take only a few weeks, this one may take longer because the incident resulted in a death, according to OSHA spokesman Edmund Fitzgerald. 

A representative from Mayer Tree Service declined to comment on the accident when contacted by phone Thursday.
