The 5-year-old child suffered life-threatening injuries when, according to witnesses, 24-year-old Emmanuel Aranda either threw or pushed the child from the third floor of the Mall of America in Bloomington, Minnesota.
Prosecutors said if Aranda is convicted, they are seeking the maximum sentence, which would be 20 years in prison. This could mean Aranda skirts an extra year of prison. The family does not know him personally.
Police arrested Aranda moments after the attack as he waited to board a light-rail train at the mall, and said he had quickly admitted to the attack.
He admitted dropping the boy almost 40 feet (12 meters), telling investigators he had been visiting the mall for years to try to talk to women, but was rejected and became angry, prosecutors wrote in a criminal complaint.
"He was enjoying a day at the Mall of America with his mom and friend on Friday morning when a stranger maliciously grabbed him and threw him over the 3rd floor balcony for no apparent reason", the GoFundMe says.
Aranda will be sentenced June 3.
He had two previous convictions for assaults at the mall, both in 2015, and had been banned from the property at one point.
The prosecutor in the case said that the boy's family backs the plea deal, according to the Associated Press.
Court records showed Aranda had been ordered to undergo psychological evaluation or treatment after those assaults, and his lawyer, Paul Sellers, said Aranda had been in mental-health court.
The boy injured in the incident was alert and conscious, according an April 26 update from a family representative.
In the complaint it said that Aranda was looking for an adult because he said they stand near the balcony but found a child to toss over a balcony instead.
"He doesn't need to be in jail", she said. "Our heart goes out to them".
