AUSTIN, Texas (KXAN) -- Investigators are working to determine how a man ended up dead after he was found suspended from a cell phone tower Wednesday.

The man was found at 7614 Thomas Springs Road, between Dripping Springs and Austin.

Authorities said the man was in his 40s and died of positional fixation, which means he was hanging upside-down for so long that he suffocated.

Investigators have called this an accidental death.

The tower is about 125 feet tall, and the man was found hanging 30 feet above the ground.

Neighbors saw him there at 8 a.m. Wednesday and called for help.

Sheriff's officials said the man was suspended from the tower during the storms, but it is not clear when he died.

''It appears that he was attached to the pole, by some wires on the pole, but he's not," said Roger Wade, spokesman for the Travis County Sheriff's Office. "There's no obvious indication that he was strangled or anything. His body is limp on the side of the pole.''

The man was not wearing any kind of harness. He was found hanging by the safety wire.

His name has yet to be released.
