  • Big night out: Christian Borda of San Francisco is accused of stabbing three people at a Daly City bar Saturday. Borda had an unrelated case dismissed in 2010 after Deborah Madden, a former crime lab worker, admitted to stealing cocaine from the lab.

So much for second chances.

A San Francisco man whose drug case in 2010 was dropped because of The City’s embarrassing crime lab scandal was arrested last weekend in connection with a triple stabbing inside a Daly City bar.

The dispute that has again locked up 22-year-old Christian Borda reportedly stemmed from a spat Saturday between his girlfriend and three men at a wedding reception in Colma. After the tiff, police said, Borda walked into Gino’s Club at 7171 Mission St. and stabbed two patrons in their midsections and a third person in the arm. Alvaro Rangel, 18, of San Leandro, helped Borda during the attack, police said.

The victims, two men from Daly City and one from South San Francisco, were taken to San Francisco General Hospital with injuries not considered life-threatening.

Police tracked down Borda, who they say wielded the knife, later Saturday and booked him into San Mateo County Jail. Rangel was taken into custody the next morning.

Borda is no stranger to the law. In 2010, he faced charges for allegedly selling marijuana. But he ended up getting off scot-free after his case was dismissed due to a crime lab scandal involving ex-criminalist Deborah Madden.

Madden, a 30-year crime lab technician, admitted to stealing cocaine from the lab on a handful of occasions in fall 2009. The tampering led to the closure of the lab’s drug testing unit in early 2010 and the dismissal of about 700 cases.

Though Borda was just one of many cases, he was prominently featured in a San Francisco Chronicle photograph about the scandal. In the picture, Borda is walking down a hallway at the Hall of Justice after his case was dismissed, according to the caption.

Borda was to enter a plea Tuesday to four felony counts, including premeditated attempted murder, but his arraignment was delayed until today, San Mateo County District Attorney Steve Wagstaffe said.

Borda remains in custody on no-bail status. Rangel pleaded not guilty Tuesday and remain in custody on $25,000 bail.
