Video here shows a pharmacist in Brazil being murdered by a schizophrenic man. The killer had been to the pharmacy earlier in the day and tried to buy pain killers for which he needed a prescription for but did not have one. The pharmacist on duty denied him, explaining to him that by law.. he could not give him opiates without a prescription. The man became angry and stormed out. A little while later, the killer told his mother he was going back to the pharmacy to kill the pharmacist who had turned him away. When his mother tried to stop him.. he shot her in the head. He made his way to the pharmacy and did just as he said, he killed the man. As of right now, the mother is still in critical condition and the killer has been arrested.
