The case of a South City resident and 19th Ave Sureño gang affiliate, Alvaro Humberto Lopez, proceeded this week.
Jury selection and opening statements were completed and prosecution evidence was presented Wednesday and Thursday. Several witnesses testified, including: Alicia MacDonald, Officer Jason Pfarr, Officer Michael Ciapas, Officer Danny Gil, and San Francisco gang expert and investigating officer Nicholas Chorley.
Narcotics Task Force expert Clint Simmont testifed with interpretation of text messages found on a cellphone that may expose where the defendent was on a drug supply chain.
Testimony related to a jail fight involving the defendent was also introduced.
In May 2011 San Francisco Police obtained a search warrant for the defendant and his residence. Police observed the defendant exiting his residence in South City and subsequently searched him and found just short of 4 ounces of heroin.
In the defendent's residence, police found an unloaded revolver and ammunition, heroin and some cocaine. Photos of the defendant with gang members were also discovered.
In an investigation of another Sureño gang member, text messages were found to and from the defendant that portray him as the source of supply to dealers.
The defendant remains in custody on $1,000,000 bail.
