Three coworkers die in CO incident

Fourth coworker remains hospitalized

PLAISTOW — Four coworkers returned from an out-of-state convention and were poisoned, three of them fatally, by carbon monoxide before they could return to work.

Fire officials yesterday confirmed the identities of the three people who were found dead Tuesday in a home at 5 Center Circle.

Kirk Walsh, 32, MaryAnn Comparato, 47, and John Adams, 28, were found dead in Walsh’s home.

A fourth victim, Keith Small, remains hospitalized at Massachusetts General Hospital. Plaistow fire Chief John McArdle said Wednesday Small was being treated in a hyperbaric chamber. A hospital spokeswoman said yesterday she could not release any information about Small’s condition.

The four victims worked at ACN, a North Carolina-based marketing company.

“All four people were on my ACN team and very active in our group,” said Frank Licata of Andover, Mass.

He said the four were staying at Walsh’s home after returning from a convention in Charlotte, N.C.

Walsh would have been 33 yesterday. He was the company’s New England regional director.

“He quit his job as plastics engineer,” Licata said. “He went to UMass Lowell and, in his late 20s, he quit his job to work at ACN.”

The victims had returned from the convention Sunday night, according to Licata.

He said he didn’t attend the convention. He said he grew increasingly concerned Monday when none of his colleagues answered their cellphones.

“It seems like they came back (from Charlotte) Sunday night and were at Walsh’s house and never woke up,” Licata said yesterday.

Police and firefighters went to the home at about 11:30 a.m. Tuesday in response to a request for a well-being check.

Walsh, Adams and Comparato were found dead. Small was alive, but unconscious. All four appeared to have been sleeping when they were overcome by the deadly gas.
