A 59-year-old man was killed after he fell into a cesspool he was helping install at a Long Island home on Wednesday. Edward Sinnott was buried under "as much as 15 feet of dirt," reports WABC 7.

Sinnott and other workers from Antorino & Sons were outside a home on Beech Place in Huntington when the cesspool suddenly collapsed around 1 p.m. According to Newsday, the cesspool "[left] a gaping hole that consumed the entire front yard and ate the top half of the driveway."

Sinnott apparently slipped in the hole. Another employee also fell, but managed to get out by "by grabbing the bucket used to scoop and dig in the area."

From Newsday:

Crews used a crane and other equipment, including a tractor-size device designed to suck up large amounts of dirt. By about 2 p.m., as many at the scene realized the likelihood Sinnott had survived faded, residents appeared visibly despondent.

“I’ve never heard of anything like this,” said Regina Sineno, 51, who lives nearby. “This is very sad.”

Sinnott's body was recovered at 7 p.m.

The Occupational Safety and Health Administration is investigating the incident. The stability of the house was also compromised and is reportedly unsafe.
