The search for Brian Laundrie was continuing in Florida's Carlton Reserve on Wednesday, a day after his fiancée's death was ruled a homicide.
The Sarasota County Sheriff's Office said members of the Sheriff's Underwater Recovery Force have responded to the reserve, which is located in Sarasota County. "This in addition to our Emergency Response Team, Air-1 & patrol," the sheriff's office tweeted.
"SURF Team members are divers called upon to search bodies of water for evidence," it said. "These highly-trained deputies work in the most difficult and challenging environments imaginable. They are on call 24/7/365."
Laundrie, who is a person of interest in the case of 22-year-old, remains missing over a week after his family said they last saw him. Law enforcement Laundrie's home in Florida for eight hours on Monday, questioning his parents and collecting evidence that could tell them what happened to Petito.
A coroner in Wyoming confirmed on Tuesday that Petito's body was discovered in a camping area within Grand Teton National Park, and the initial manner of death was ruled a homicide.
The FBI in Denver asked anyone who was in the area between August 27 and August 30 to contact investigators.
"The FBI and our partners remain dedicated to ensuring anyone responsible for or complicit in Ms. Petito's death is held accountable for their actions," the FBI in Denver said in a statement Tuesday.
Petito's last known contact with family was in late August while she was in Grand Teton National Park, authorities said. She was reported missing on September 11 — 10 days after Laundrie returned home from a cross-country trip without her.
"(The) first word that popped in my brain was 'coward,' to be honest with you," Petito's friend, Rose Davis, told CBS News. "You're supposed to love her. You're supposed to marry her. I want to text him and just be like, 'Please, please give me something.'"
