Police say officers have also been targeted in Tennessee, Georgia and Missouri in the aftermath of two high-profile killings of black men by law enforcement.
In a fourth attack early Friday, a motorist fired at a police vehicle as the officer drove by.

Hancock and Beck were taken to a local hospital. One woman died, and three others, including a police officer, were injured.
