California Man Charged In Pittsburgh Drug Deaths:  Three people died and four others overdosed after ingesting what police now believe was fentanyl-laced cocaine in a Pittsburgh apartment early last Sunday.  Torsten Ove and Shelly Bradbury of the Pittsburgh Post-Gazette report that suspected California drug dealer Peter Rene Sanchez Montalvo has been charged with distributing the drugs to a group attending an after-party in his apartment, following a concert at a local club.  Sanchez Montalvo, who had a California driver's license, was renting the apartment under a fictitious name, which is common among drug dealers.  A witness reported that, after bragging about how much money he was making, he pulled out a box, scooped out some white powder with a knife and walked around the room letting his guests snort some of it.  The witness provided police with a video showing Sanchez Montalvo serving the powder to people at the party.
