July 30 (UPI) — The husband of a missing Cary, N.C., woman in Granada said he believes there is no foul play in her disappearance.

Elizabeth “Liz” Waddell, 43, was last seen swimming near Grand Anse Beach in Grenada on July 22 while on vacation with a friend.

Her husband, Cailen Waddell, wrote on his website Wednesday: “After careful and thoughtful consultation with family, local authorities, the U.S. Embassy, and others here in Grenada, I join authorities in believing there was no foul play. Liz was last seen swimming in the ocean near Grand Anse, around 5:30 p.m., far from shore. She communicated her confidence in her swimming and location, as well as the beauty of the island.”

Grenada police commissioner Randy Connaught said Liz Waddell remains missing, but investigators are hopeful she will be located.

“Investigators have also received several eyewitness accounts indicating that she was swimming in the open water,” Connaught said in a Tuesday press conference.

Liz Waddell’s friend Amanda Romano-Harmon told WRAL that Liz’s friend on the trip with her, Heather, finished online coursework then went to look for Liz. She only found Liz’s towel on the pier.

After a few hours, she called Cailen Waddell, who was at work in North Carolina.

“She was starting to panic because she knew Liz didn’t have her phone or anything with her,” Romano-Harmon said. “And so they wound up filing a missing persons report right away.”

Cailen Waddell said on his website that travel was important to the couple.

“I am heartbroken that she is missing. Those of you who knew us best knew our commitment to each other, to travel, to nature, and exploring the world as a team. I am so thankful for the outpouring of community support. It is far beyond what I ever expected, please continue to send love, good thoughts, and whatever positive vibes best fit your belief system,” he wrote.
