Three people - including a Texas police chief - have reportedly taken their lives after their email addresses were part of the Ashley Madison hack last week.
Hackers claimed they released details of more than 30 million people who had accounts with the website, which spouses use to find affairs.
Captain Michael Gorhum, who had worked for the San Antonio Police Department, died from a self-inflicted gunshot wound last Thursday, KSAT reported.
His official email address was among those released in the hack, according to the IB Times. INSIDE EDITION has confirmed that an email address in his name is listed.
But it has not yet been confirmed that the hack played a part in his death. Ashley Madison does not require users to verify email addresses, so it is also unknown if he was the one who used the email address to create an account.
One of his colleagues wrote on Facebook: "Rest in Peace Captain Mike Gorhum. You truly are one of the guys, I’ve most respected in my Law Enforcement Career, no task too big, no goal too lofty.
"Never backed down, always had your partner’s back or when you were in charge, your Officer’s back. Whatever it was, I wish one of us could have reached you, could have told you, 'It will be OK.'"
On Monday, Canadian police said the hack has also led to two unconfirmed reports of suicides in the country.
Toronto Police acting staff-Supt. Bryce Evans said the hack has had an "enormous social and economic fallout."
"This hack is one of the largest data breaches in the world," Evans said. "This is affecting all of us. The social impact behind this leak, we're talking about families, we're talking about children, we're talking about wives, their male partners."
He did not offer details of the unconfirmed suicides but said there are also confirmed cases of criminals trying to extort the website's users by threatening to expose them unless they pay up.
Evans told the hackers what they are doing is "illegal and will not be tolerated."
The company behind Ashley Madison is now offering a $500,000 Canadian (US $378,000) reward for information leading to the arrest of members of a group that hacked the site.
