A record-breaking $4 billion bond was set Tuesday for a Killeen man who turned himself in to police last week.

Antonio Willis, 25, is in jail for the murder of Donte Samuels who was found dead in the yard of a Killeen home.

Newly-elected Justice of the Peace Claudia Brown set the record bond, which is the largest in Bell County history and possibly the U.S.

According to law firm Nuttall & Coleman, the highest bond set in U.S. was $3 billion for New York real estate heir Robert Durst. Durst was charged and later acquitted in 2003 in the murder of his neighbor, Morris Black.

Due to the high number, the jail’s booking software could only set the total bond amount at $1,000,000,999.

Brown posted a series of updates on her Facebook profile.

A legal source said that if a high bond is set, it is generally because the court Is trying to technically obey the law and off a bail amount while also ensuring the safety of the community because it is highly unlikely for anyone to meet that amount.
