East St. Louis, IL (KMOV) - East St. Louis police are investigating the suspicious death of a two year old boy.

His 4-year-old brother is suspected of killing him, and his mother tells News 4 that he was pretending he was a professional wrestler.

Jacqueline Davis says she came out of the shower and found her two-year-old son Jacquion unresponsive on his bedroom floor.

She says her four-year-old son told her and police that he was pretending to be WWE professional wrestler who he watches dominate opponents on the Friday night show.

The 4-year-old allegedly choked his brother with part of a curtain.

Rescuers flew Jacquion by helicopter to Cardinal Glennon Children's Hospital where doctors treated him in intensive care for four days until he died Tuesday.

Sources familiar with the case tell News 4 that autopsy results could take two weeks and that a police investigation is pending.

The victim's mother says she's convinced exposure to professional wrestling played a part in the tragic murder.
