The man convicted in July in a 2009 Tenderloin homicide was sentenced today to 51 years to life, according to the District Attorney’s Office.
Alex Herrera, 56, of San Francisco, was convicted July 11 in the Sept. 10, 2009, murder of John Montgomery, 37 at the time, in a Tenderloin residential hotel, spokesman Max Szabo said in a statement.
The two men were reportedly involved in an argument over a payment for drugs that at some point resulted in Montgomery being stabbed several times, which led to his death.
A knife found nearby the hotel with DNA evidence linking it to Herrera was a key piece of evidence in his conviction, Szabo said.
“Due to the collective efforts of the Police Department and my office, this dangerous man is no longer on the streets of San Francisco,” District Attorney George Gasón said. “I am pleased that justice has been served for the victim’s family.”
