The family of missing American Elizabeth Waddell says it now believes there was no foul play involved in her disappearance in waters off Grenada’s Grand Anse Beach.

In a statement, Waddell’s husband, Cailen Waddell, said the family reached the conclusion after consulting with Grenadian authorities, the US Embassy and other officials involved in the search.

“After careful and thoughtful consultation with family, local authorities, the US Embassy, and others here in Grenada, we believe there was no foul play involved,” he said in a statement posted on July 29.

He stressed, however, that the missing person investigation remains active.

“We are specifically hopeful to determine her actions between the time she was last seen on video and the time she was seen in the water around 5:30, as well as any further sightings. No detail is too small,” he said.

Waddell’s relatives left Grenada on Friday after spending about a week on the island assisting with search efforts.

“We have done what we can here, and the investigation will continue,” Cailen Waddell said in a statement issued on July 31.

He also thanked the Royal Grenada Police Force, the US Embassy, members of the public and the media for their support during the search.

“To the Grenadian people: Thank you so, so much. Every Grenadian we have encountered has warmly welcomed us and expressed so much genuine concern for Liz,” he said.

A day earlier, Waddell’s sister, Anna Watkins, said she was leaving Grenada with a “broken heart” but remained hopeful that her sister would be found.

“While the missing person investigation remains open, I am grieving. I am devastated, my heart hurts, and the world around me feels like a blur,” Watkins wrote.

She described her sister as someone with a “magical spirit.”

“She’s not lost. She’s exploring the sea, still sharing her magic with those around her,” she added.

Waddell, a physical therapist from North Carolina, was reported missing after she was seen jumping from a jetty into the sea near Grand Anse Beach around midday on Wednesday. 

Her last confirmed sighting came about five-and-a-half hours later, when she was seen in open water.

According to reports in Grenadian media, Waddell was approached by people on a jet ski and a dinghy who asked if she needed assistance. 

She reportedly declined, telling them she was fine and that she was a “good swimmer.”

Investigations into Waddell’s disappearance is ongoing.
