Lawrence

performer who also doubled as a security guard at Fredbears family diner 

died on stage whilst performing at a child's birthday party due to springlock failure 

didn't seem to have any family so his death was easily swept under the rug

liked the two animatronics a lot, saw them as friend even if they were just suits or robots. Hurt himself a lot on the job

due to being associated with the spring Bonnie suit, he was a main suspect in a slew of child disappearances at the restaurant

a victim of homicide or a freak accident. the answer is lost to time.
