Miami , Florida ( CNN ) -- The father of a 2-year-old Florida boy has admitted to the near-fatal beating of his son while teaching the child how to box , officials said Wednesday . Lee Willie Dejesus , 23 , of Homestead was arrested Tuesday and charged with aggravated child abuse and child neglect , according to the criminal complaint against him . Miami-Dade police said the incident occurred Monday night when Dejesus was watching the child while his mother was at work . Dejesus told police that he put on boxing gloves and struck the child about 15 times on his face , head , torso and shoulders over a period of 15 minutes , punching him so hard at one point that the boy fell off the bed and struck his head on the tile floor . The child was rushed to Children 's Hospital where he underwent surgery for bleeding on the brain . The boy -- identified by CNN affiliate WSVN as Willy Brown -- was on life support Wednesday and not expected to recover from his injuries , said Ed Griffith , spokesman for the Miami-Dade state attorney 's office . Griffith said the boy `` may be brain dead , '' and the attorney 's office expects to file first-degree murder charges against Dejesus as early as Wednesday night or Thursday . The complaint alleges that Dejesus waited to call for medical help for as long as an hour after the boy became unresponsive . He eventually called 911 after the boy 's lips became blue , according to the complaint . Dejesus initially told police that the boy was beaten by a babysitter before admitting he did the beating , the complaint says . He is being held at a pretrial booking facility on $ 50,000 bond on the aggravated abuse charge and $ 7,500 on the child neglect charge , jail records show .
