Police are investigating a third Los Angeles medical marijuana dispensary shooting.

An employee at a San Fernando Valley dispensary was shot in the face and critically wounded during a robbery Saturday night. The gunmen escaped with $11,000.

Three days earlier, two people were shot to death and another was wounded at pot dispensaries in Hollywood and Echo Park.

Police Capt. Kevin McClure says there doesn't appear to be any connection between those shootings and the Saturday case. But he says it is "a disturbing pattern."
