The officers found two people believed to be the intended targets. Both were unharmed, said Sgt. Ed Soares of the Menlo Park Police Department.
Two unknown male suspects were seen leaving the area in a dark blue American-made sedan, Sgt. Soares said.
Police have not determined a motive for the shooting, he added.
Anyone with information is asked to call Menlo Park police at 330-6360.
May 21: Library closing
The Menlo Park public library on Alma Street closes on May 21 for renovation.
When it reopens on June 18, patrons will see a new circulation area and an easier checkout system via radio frequency identification tags, according to the staff.
The outside book drop will stay open to allow patrons to return items, and the Belle Haven branch, at 413 Ivy Drive, will extend its hours until the main library is back in business.
