Las Vegas Stephen Paddock gunman was reportedly prescribed anti-anxiety medication before the attack

Stephen Paddock, the accused shooter in the Las Vegas massacre, was reportedly prescribed an anti-anxiety drug in June, the Las Vegas Review-Journal reported.

The outlet reported the news after obtaining records from the Nevada Prescription Monitoring Program. The records show Paddock had been prescribed 50, 10-milligram diazepam tablets on June 21st.

According to the outlet, the brand name for the drug is Valium and it is a sedative-hypnotic drug which can cause aggressive behavior when abused and trigger psychotic episodes. Those experiences are further amplified with alcohol.

A retired FBI profiler, Jim Clemente, said in an interview that investigators may be able to prove if Paddock had some kind of neurological disorder if his suicide did not destroy his brain.

“The genetics load the gun, personality and psychology aim it, and experiences pull the trigger, typically,” Clemente said, while adding that Paddock’s father, an alleged a bank robber, was diagnosed a psychopath.

Paddock’s brother insists there were no underlying signs anything was ever wrong with him. A gun shop that sold Paddock a gun says he passed his background check.

Police say they found 19 guns, along with explosives, at his home. Another 23 guns were found in his hotel room.

Now, as investigators continue to comb through the clues, determining why Paddock would have been prescribed Valium may determine a motive to the killing of at least 58 innocent lives.
