Tourists at the Sandals resort in the Bahamas where three Americans were mysteriously found dead last week have been complaining about the intense smell of bug repellant.

While talking to NBC News, multiple guests said that there was a “strong odor” of insecticides. The Bahamian authorities are now investigating the deaths of the US citizens, who have been identified.

The latest finding could act as a strong lead in the bizarre deaths.

In 2016, the parent company of pest control company Terminix settled for $87 million with an American family poisoned by an insecticide while on a Caribbean vacation. 

The victims’ families and the Royal Bahamas Police Force are trying to piece together how the three people died.

Authorities are also looking into possible issues arising with the air conditioning in the tourists’ rooms that may have played a role.

Royal Bahamas Police Force Commissioner Paul Rolle identified the dead victims as Robbie Phillips, 65, and Michael Phillips, 68, both from Tennessee, and Vincent Chiarella, 64, from Florida. The couple from Tennessee were owners of a travel agency based in Maryville.

“Our hearts are grieving and broken but full of hope,” their daughter, Kali Hanson, told Knox News, on Monday afternoon. “We know our mom and dad are experiencing fullness of joy in our heavenly father’s presence. We already miss them terribly. Our parents left a legacy of faith in Jesus and generously loved their family and friends.”

The bodies of three Americans were found at the Sandals resort in the Bahamas in two separate but connected villas. They died just hours after separately seeking medical treatment because they were feeling unwell. A cause of death is likely to be revealed after the autopsy results are out.

A honeymooning Arizona couple staying at the property said Tuesday that everyone at the luxury getaway has been “kind of just hush-hush” about the matter.

“It is a scary feeling being here right now,” Carley Shimkus told Fox News. “And it’s a little uncomfortable for both of us … I want this to be the happiest time in my life, but it’s kind of hard, though, just with the situation that is going on.”
