Prosecutor's witness in Kate Steinle trial sued for lying

SAN FRANCISCO (KGO) -- A prosecution witness in the Kate Steinle murder trial is being sued for lying in another, unrelated case.

John Evans is a retired CSI unit officer with the San Francisco Police Department. He was brought in because of his experience in ballistic and firearms investigations.

Evans testified that the defendant, Jose Ines Garcia Zarate, pointed the gun in the direction of Steinle, pulled the trigger and killed her.

But, on Tuesday, lawyers in a completely different case will be in federal court in Oakland to argue that Evans and other SFPD officers violated their client's constitutional rights.

The case involves a man by the name of Jamal Trulove, who was convicted of murder in 2010. That conviction was overturned, and Trulove was acquitted in a second trial.

Evans testified for the prosecution in both trials. It was later discovered that Evans misrepresented the facts under oath.
