HAINES CITY, Fla. (WTSP) -- Polk County deputies have found the body of 28-year-old Yanela Lorente, who has been missing since Sunday, and they say she took her own life.

The body was found in a heavily wooded area of the Hilochee Wildlife Management Area off Old Polk City Road east of State Road 557.

After an autopsy, the coroner said the cause of death was a self-inflicted gunshot wound.

"This was not the outcome we were hoping for. We are deeply saddened for Yanela's family. Please keep her family in your thoughts and prayers during this difficult time." said Sheriff Grady Judd.

Haines City police, Polk deputies and the Florida Fish and Wildlife Conservation Commission were assisting in the search.

Haines City Police Chief Gary Hester said information from residents placed Lorente's car at the park about 7 p.m. Sunday.

Police had been searching for five days. She was last seen Sunday leaving her home. She lives there with her boyfriend and male roommate, and they said she left after an argument.

Lorente's family spent the past five days outside the police station. When they're not there, they were handing out flyers and putting them up around town.

“It's terrible not knowing where she is,” Lorente’s sister, Yani Lorente, said. “You just want to scream.”

Lorente hasn't been seen since Sunday, and her mom and sister haven't heard from her since Saturday.

“Sometimes you lose hope,” Lorente said. “It's already been five days.”

Police, along with the Florida Fish and Wildlife Conservation Commission and the Polk County Sheriff's Office, have been searching a nature preserve. Her boyfriend found her car there, but not her.

“Suspicious is the fact that she normally calls her mom every day, and her sister three or four times a week,” Deputy Police Chief Jim Elensky said. “None of that's occurred since Sunday afternoon.”
