"He had a longer beard. He stated he cleaned up or trimmed his beard for his work on Tuesday. He looked different than he did on Monday," Kelly said.
Meanwhile, the entire community of Borough Park was searching for the missing boy. In his chilling confession letter, Aron indicated what allegedly drove his to commit the murder.
"When I saw the flyers I panicked. When I got home he was still there, so I made him a tuna sandwich. I was still in a panic. That is when I went for a towel to smother him."
By 2:30 on Wednesday morning, Aron was arrested and the boy's body was found. Amidst a mob, Aron was taken for DNA testing in attempts to link him to any other missing person cases.
Commissioner Kelly echoed the feelings of many across the community and country that are shocked by the young boy's death.
"There's usually some sort of irrational twisted logic that's given to why a violent event took place. Here it defies all logic and I think that's what's really so terribly disturbing about this case," Kelly said.
The final words in his confession letter indicate that Aron may not fully comprehend the magnitude of the crime he has confessed to.
"I understand this may be wrong, and I'm sorry for the hurt that I have caused," the letter read.
