WALLA WALLA -- Four reported gang members are behind bars for a July drive-by shooting in Walla Walla.

Officers from three agencies rounded up the suspects Friday night in Milton-Freewater. The first arrest was made at 10:45 p.m. with the last suspect in custody about three hours later, said Walla Walla Officer Bennett.

The shooting occurred at 5:40 p.m. July 28 at Howard and Tietan streets. Police report that gang members were chasing members of a rival gang when gunfire broke out.

No one was injured in the shooting, but a bullet struck a nearby home, Bennett said.

Daniel Ramos-Lara, 26, and Francisco Casillas Jr., 30, were booked Friday night into the Umatilla County jail each on four counts of first-degree complicity to assault, complicity to drive-by shooting and complicity to riot.

Two of the suspects are juveniles, ages 15 and 17. Those boys are being held in a juvenile detention facility on riot charges.

The roundup Friday was a culmination of a two-month long investigation with support from Milton-Freewater police and Walla Walla County sheriff's deputies, Bennett said.
