ST. JOHNS COUNTY, Fla. -- A man is charged with animal cruelty and sexual activity involving an animal, according to a St. Johns County press release.

The investigation began Monday when a 48-year-old St. Johns County man filed a report with the SJCSO. The release detailed that the man let his two dogs outside on July 20 before a storm. One of the dogs went into the suspect's yard and didn't return.

The release detailed that the suspect was allegedly carrying one of the dogs from his trailer and said he found her in a shed. The man noticed that the dog was not acting herself and found injuries to her private area.

Animal control was contacted and advised the man to take her to an emergency vet. The veterinarian was suspicious of animal abuse and cruelty, the release said.

The Special Victim's Detectives investigated the case and obtained a warrant for James Lee Lyons, 52, Friday.

Lyons is a registered sex offender the release detailed. He was previously convicted on charges of attempted sexual battery on a child and sexual act with a child while in a familial role in 1998. The release said Lyons was released in June 2011 after serving more than 13 years in prison.

Detectives are continuing the investigation and Lyons is currently at the St. Johns County jail.
