he was "looking for someone to kill, but it did not 'work out,'" according to a probable cause document released Monday. He said he came up with a plan to "kill someone at the mall" on Thursday and indicated that he was angry because women at the mall had rejected him.

"He said he planned to kill an adult, because they usually stand near the balcony, but he chose the victim instead," the document said. "[He] indicated he had been coming to the mall for several years and had made efforts to talk to women in the mall, but had been rejected, and the rejection caused him to lash out and be aggressive."

Investigators said he repeatedly acknowledged he'd come to the mall with intentions to kill and signaled thathe was "aware that what he was doing was wrong," according to the charging documents.

Aranda was previously banned from the mall for throwing water in a woman's face and destroying property. Police said he also had a warrant for his arrest in Illinois on assault charges.

Police said surveillance video from the scene showed Aranda entering the third floor of the mall and looking over the balcony several times before he approached the 5-year-old victim and his mother.

The victim's mother said she noticed the suspect getting "very close to them" and asked if she and her son should move, the documents said. Aranda remained silent as he lifted the boy up over the balcony, "without warning," and threw him down to the first floor, according to the charging documents.
