Four men linked to a fatal North Beach shooting in April have been charged and are expected to be arraigned in court on Thursday, the San Francisco District Attorney’s Office has announced. 

The shooting, which left 23-year-old Isaiah Thomas of Suisun City dead and four others injured on April 23 after a botched robbery.

“Addressing gun violence is a top priority for my administration,” District Attorney Brooke Jenkins said in a statement.  “We will ensure that there is accountability and appropriate consequences for heinous crimes like this one that gravely threatens residents, visitors, businesses and our communities.”

The men charged include 22-year-old San Francisco resident Nkeosi Jackson, Oakland residents 22-year-old Malachi Lefiti and 20-year-old Marilyn Sahugun-Lopez. Suisun City resident Jeremiah Thomas has also been charged. 

Lefiti and Jackson are also expected to be charged with gang enhancements, but police will not reveal which gang they are allegedly affiliated with. 

Police say Lefiti, Thomas and another suspect tried to rob several people at gunpoint near Grant and Columbus avenues at around 11 p.m., but their efforts backfired. 

Lefiti and Sahugun-Lopez were injured in the shooting and transported to a local hospital. 

Lefiti’s father Mike Lefiti was killed in a mass shooting at a UPS warehouse in 2017 by UPS worker Jimmy Lam, who fatally shot three of his colleagues and injured two others before killing himself.

Lefiti was arrested initially but released without being charged.
