KENNEWICK, Wash.- A rash of church burglaries has police putting out a warning .
Many churches leave their doors open so people can walk in and worship anytime, but that leaves them vulnerable to vandals and thieves.
Kennewick's First Lutheran Church was just hit, along with the Free Will Baptist Church.
Thieves stole high end stereo equipment, which police say is easy to pawn.
Police don't have any suspects.
