A former dishwasher who allegedly threatened to shoot up and blow up the restaurant where he used to work in a Las Vegas casino is still behind bars. The restaurant employee's nameless cell phone received the calls. Due to the absence of caller ID on his cell phone and his lack of knowledge regarding the caller's identity, the employee didn't answer the first two calls. It's unclear how the suspect came to know the employee's mobile number. He was still being held as of Wednesday, and his court date on June 6 is set.
