Serrapio allegedly wrote on his Facebook page last Tuesday: “Who wants to help assasinate Obummer while hes at UM this week?”

On Thursday, he allegedly followed up with another post that read: “If anyones going to UM to see obama today, get ur phones out and record. Cause at any moment im gonna put a bullet through his head and u don’t wanna miss that! Youtube!”

Secret Service agents based in Miami went to Serrapio’s home on Thursday, the day of Obama’s visit to Miami, where Serrapio and his mother consented to their search of the house.

Pellet guns were found in the home he shares with his family, along with evidence that Serrapio sent the social media messages, according to the criminal complaint filed by Secret Service in Miami and released on Tuesday. The Secret Service also reported in the document that Serrapio admitted to posting the threatening status updates.
