Chino Police Chief Miles Pruitt, along with the FBI and authorities from Idaho and Washington, plan to appear for a press conference at the Chino Police Department.
The robber, dubbed the "AK-47 Bandit" because of the weapon he used during the holdups, remains on the loose. The FBI has posted a $50,000 reward for his capture.
The man shot a Chino police officer after he robbed California Bank and Trust at 5455 Riverside Drive on Feb. 29.
The officer, who suffered at least one gunshot wound, drove himself to a hospital about a block away.
Police suspect the man or an accomplice called 9-1-1 before the heist, reporting there was a bomb on the south end of the city to lure officers away from the bank.
Authorities suspect he tried to rob Tri Counties Bank in Sacramento on March 9, and then successfully robbed Bank of the West in Vacaville three days later.
The FBI said a Nissan Maxima, the same type of getaway car used in the Chino robbery, may have been used in both Northern California incidents.
For nearly four months, the man appeared to have stopped his spree.
But then on July 6, a robber with an AK-47, hit a Chase bank in North Bend, Wash. He threatened to shoot tellers if they didn't hurry in giving him cash.
He carried bills out of the bank by hand, since he didn't have a bag.
In that heist, he used a dirty, reddish-orange Jeep Patriot or liberty as a getaway vehicle.
The FBI said another robbery occurred Nov. 7 at the East Idaho Credit Union in Rexburg, Idaho. The robber, armed with an assault rifle, ordered employees and customers into the vault. He fled in a dark blue sedan with tinted windows and a red and blue license plate.
In some of the incidents, the robber wore a blue bullet-proof vest with the word "SHERIFF" across the chest in bright yellow. Surveillance video also showed he wore a dark, short-sleeve collared shirt under the vest, blue pants and a black full-face ski mask.
