SAN FRANCISCO (AP) A man in a wheelchair who was shot by San Francisco police has been acquitted of charges that he stabbed an officer just before the shooting.

A jury acquitted 56-year-old Randal Dunklin on Tuesday while deadlocking on two additional counts of felony assault and a charge of resisting police.

Dunklin was convicted of vandalism and brandishing a knife, misdemeanors.

Authorities say Sgt. Noah Mallinger shot Dunklin on Jan. 4 outside a city Public Health Department building after Dunklin rose from his wheelchair and stabbed another officer in the arm.

Police were responding to reports of a man throwing concrete blocks at people and slashing tires. The officer who was stabbed required 21 stitches.

District Attorney George Gascon said he was disappointed with the verdict. Prosecutors are considering retrying Dunklin on the counts the jury deadlocked on.
