Authorities said the body of a 2-year-old Florida boy was found Friday night in the mouth of an alligator.

The St. Petersburg Police Department said Taylen Mosley was found in Lake Maggiore and that his father, 21-year-old Thomas Mosley, had been charged with two counts of first-degree murder for the deaths of his young son and wife.

"It is with great sadness that I have to tell you that we found the body of Taylen Mosley. My condolences to his family," Chief Anthony Holloway said in a statement.

This announcement comes following a desperate search for the child and after his mother, 20-year-old Pashun Jeffrey, was found stabbed to death in her St. Petersburg apartment on Thursday afternoon.

Search and Rescue of Central Florida searched using cadaver dogs and the Florida Fish and Wildlife Conservation Commission assisted with the reptile.

Police said that the investigation led detectives to search Dell Holmes Park, 2741 22nd Street South and Lake Maggiore. 

Following a day-long search, evening officers were alerted to an alligator seen with something in its mouth. The alligator was killed in order to retrieve the body.

"We are sorry it has had to end this way," Holloway said during a Friday night news conference, telling reporters that Mosley is hospitalized with cuts on his hands and arms and has refused to talk to investigators. He does not yet have a lawyer to speak on his behalf.

Police have not revealed how his son was killed or whether the alligator had played a role in that.

Jeffrey, who worked at a CVS store, and her son were last seen by family members at around 5:20 p.m. ET on Wednesday. While neighbors heard a loud commotion near their apartment at around 8:30 p.m. the same night, the police were not called.

The pair had just moved into the apartment complex about a month ago.
