The widow of a cop killed while escorting President Obama's motorcade has filed a lawsuit in his death.  Jupiter Police Officer Bruce St. Laurent died during a 2012 visit by Obama.

St. Laurent's motorcycle was struck by a pickup truck while he prepared to shut down a stretch of I-95 ahead of the motorcade.  His wife is suing the Palm Beach County Sheriff's Office, claiming they were negligent in allowing that truck to enter the highway.

The lawsuit seeks unspecified damages.
