Deputies say the man wanted for stealing a car with a baby and an autistic man inside apparently killed himself in St. Petersburg Saturday morning.

Sloan Maybeck, 44, was wanted on two counts each of attempted murder and kidnapping, as well as one count of carjacking.

On Saturday morning, officials said they found a man hanging from a belt behind the 7-11 located at 6161 Fourth St. N in St. Petersburg. That man was later identified as Maybeck.

Deputies began looking for Maybeck shortly before 6 p.m. Friday, after they said he stole a car that was left running outside a bait store on State Road 60 near Bartow. In the process, deputies say he dragged the female driver of the car and a witness who had stopped to help.

The autistic man and the baby were inside the car at the time. The man and baby, who are both siblings, were later found unharmed in Bartow. The oldest sibling told his father James Joiner that he was just worried about the baby.

"He just said that he was trying to stay calm and protect the baby. Do the right thing," Joiner said of his son. "He was a little bit nervous of course as we all would be. But, he did his job, which was to protect his little sister and get them home safely."

The stolen car was recovered in Bradenton, where deputies learned Maybeck had stolen another vehicle.

"Maybeck had a violent past and it appears that violence led to his own death by his own hands," Sheriff Grady Judd said in a statement. "He was facing serious criminal charges after stealing a car with a baby and a disabled adult inside.  Being concerned that his violent acts of desperation would result in more victims, a multi-jurisdiction search was conducted throughout the night.  Ultimately his irrational acts led to him taking his own life."

Polk deputies said the death investigation is currently being conducted by the St. Petersburg Police Department.

Joiner said this has all been an upsetting experience. But, it is one that will keep them on edge at least for a while.

"[It] keeps us more aware that anything can happen any given time to me you or anybody around any store any moment," Joiner said. "[It's] a very traumatic situation, but we have peace and closure right now and we're putting it in our rearview mirror."
