Arizona interstate re-opened after ricin scare

A stretch of Interstate 15 along the Arizona-Utah border was reopened early on Wednesday after the northbound and southbound lanes were closed on Tuesday in the aftermath of a ricin scare.

Troy Eugene Williams of Florida allegedly robbed a bank using a bomb threat on Tuesday. Williams was pulled over on the interstate around 1 p.m. on Tuesday in connection with the incident and a later carjacking in Mesquite, Nev. When police stopped the car in Arizona and approached the vehicle, the driver committed suicide with a gunshot to the head, the Salt Lake Tribune reports.

The Arizona Department of Public Safety ordered the interstate's closure in the Virgin River Gorge until 4:30 a.m. on Wednesday while hazmat emergency teams examined the suspect's vehicle for the deadly toxin and explosives that were suspected to be in the car. Williams' family warned that the suspect boasted of having a large quantity of hand grenades and ricin. While there were two suspicious boxes in the back of the car, the public safety department determined that the substance in the car was harmless. In addition, no explosives were found in the car.

After thorough examination, the vehicle was towed away and the interstate was reopened. The Mohave County Sheriff's Office is further investigating the incident, according to the Salt Lake Tribune.
