Marjorie Reitzell, of Redwood City, allegedly had a blood-alcohol level of more than twice the legal limit of .08 percent when her 1998 Honda veered into the bike lane on Chilco Street at about 7 p.m. on Thursday, San Mateo County District Attorney Steve Wagstaffe said.
Reitzell, who was on probation for a 2012 DUI conviction, struck 45-year-old Kamal Singh, and 50-year-old Balbir Singh from behind, throwing the couple into the air, according to Menlo Park police Cmdr. Dave Bertini.
The victims, who have three teenage children, died at the scene. The Singhs' dog was injured in the collision and was taken to the Peninsula Humane Society for treatment.
Wagstaffe said Reitzill continued driving and struck a car carrying four teenagers, causing minor injuries.
She then crashed into a tree, where she was found by first responders and taken into custody by police.
Reitzill has been charged with two counts of gross vehicular manslaughter and two counts of DUI causing injury, Wagstaffe said.
She is being held in San Mateo County Jail on $2 million bail.
Reitzill was due to be arraigned on Monday, but asked for a continuance due to a medical issue just before the proceeding, Wagstaffe said.
