A father accused of stabbing his girlfriend to death and then tossing his two-year-old son into a lake was seen in a wheelchair with heavy bandages wrapped around his arms in new footage from his booking.

Thomas Mosley, 21, was charged with two counts of first-degree murder after the body of Pashun Jeffrey, 20 was found in her apartment in St Petersburg on Thursday. Her body had been stabbed over 100 times.

Mosley was arrested after checking himself into a hospital for wounds on his arms, which authorities said were 'consistent with injuries caused by slippage during a knife attack.' 

The body of his son with Jeffrey, Taylen, was discovered hours later in the mouth of an alligator in a lake that Mosley allegedly pitched the boy into.

In the booking photo, Mosley wore a pair of scrubs and a dour expression as he was wheeled into the room by officers. His bandaged writs appeared to be zip-tied together, and he seemed to need help from officers to stand before they began their procedures.

Thomas Mosley, 21, was charged with two counts of first degree murder following the deaths of his two-year-old son and the child's mother

Mosley had been at Jeffrey's home in the late afternoon last Wednesday with her family to celebrate the young father's birthday. 

Several hours later, Mosley arrived at his mother's house with 'severe lacerations to both of his hands and arms consistent with injuries caused by slippage during a knife attack.'

Prior to arriving at his mother's house, Mosley travelled to the Lake Maggiore area and, in a premeditated fashion, threw his son into the body of water, an action police classified as first degree murder.

Mosley then arrived at his mother's house at around 9pm and from there went to the hospital to be treated for his wounds before being arrested. He was reportedly not cooperative with authorities.

A GoFundMe established by the mourning family that has now raised north of $20,000, described Jeffrey as 'dedicated' to making life better for her son.

Taylen was described as a 'sweet and happy toddler' who would 'grab anyone's phone and pretend to call his mom' while she was at work.

'To see them together and their love for each other was a blessing. We will remember their love and will keep them in our hearts,' it reads.

Family members last saw Jeffrey and Taylen on Wednesday March 29 around 5.30pm. They called for a welfare check on the young mother the next day when they were unable to contact her.

Neighbors said they overheard a loud commotion near the apartment at around 8.30 on Wednesday night, but police were not called.

The next morning, Jeffrey's mother called the apartment manager for a welfare check after her daughter missed their daily FaceTime call.

Pashun Jeffrey, 20, was mother to two-year-old Taylen Mosley. She was known as a loving and devoted single mother striving to provide a better life for her son

Law enforcement and family members initially hoped to find Taylen alive when his body was spotted being carried by an alligator in the nearby lake

Jeffrey's body was found in the bathroom, which was described as a 'very violent' scene and included a bloody fingerprint on a cleaning bottle that had been 'intentionally placed under a bed,' according to an affidavit.

There was also a bloody shoe print with the 'Gucci' emblem on the bathroom floor where the victim was found. 

Law enforcement and family members initially hoped to find Taylen alive when his body was spotted being carried by an alligator in the nearby lake. 

An officer shot the reptile in order to retrieve the body. 

'We are sorry it has had to end this way,' St. Petersburg Police Chief Anthony Holloway said at a press conference on Friday night.

Sniffer dogs, drones and search teams had been dispatched to find the missing toddler. 

He had celebrated his second birthday just 19 days prior to his murder.
