A newly released affidavit from the St. Petersburg Police Department has shed light on the circumstances surrounding the deaths of a young mother and her two-year-old son whose body was found in the mouth of an alligator.

Taylen Mosley, the two-year-old boy whose body was found in the mouth of an alligator March 31, was allegedly placed or thrown into a lake by his 21-year-old father, Thomas Isaiah Mosley, CNN reported Monday. That action inflicted “mortal wounds” on the child, causing his death, the affidavit stated, according to CNN.

The tragic deaths of Taylen and his 20-year-old mother, Pashun Jeffrey, allegedly occurred after Jeffrey’s family had gathered to celebrate Mosley’s birthday March 29. The following day, after Jeffrey’s mother couldn’t reach her daughter, the family went back to the apartment and reportedly discovered blood on the sidewalk leading to Jeffrey’s place. The apartment management office was notified and upon entering the apartment, they discovered Jeffrey on the floor of her bathroom, reportedly stabbed in excess of 100 times, the affidavit states.

When law enforcement officials arrived, they discovered a cleaning bottle “intentionally” hidden away under a bed stained with a bloody fingerprint police linked to Mosley, the affidavit states. In addition, police found a bloody “Gucci” shoe print on the floor of the bathroom near Jeffrey’s body.

On the evening of March 29, Mosley reportedly arrived at his mother’s home with “severe lacerations to both of his hands and arms consistent with injuries caused by slippage during a knife attack,” the affidavit reads. As a result, Mosley was admitted to a local hospital for treatment. Prior to the arrival at his mother’s home, Mosley reportedly traveled to Lake Maggiore, the affidavit read. Taylen’s body was found in an alligator’s mouth in Dell Homes Park, which borders the lake, CNN reported.

“Due to the extremely serious allegations surrounding these tragic losses, our investigation is currently focused on gathering information about the facts and circumstances of the case, as well as our client’s mental state,” a spokesperson for Sixth Judicial Circuit Public Defender Sara Mollo said in a statement, according to CNN.

Mosley remains in the Pinellas County Jail after his arrest and is scheduled for a bond hearing on April 11, according to the outlet.
