Four days after the police shooting in Sioux City, there is still no sign of the accused shooter, Jamal Dean.
But authorities are hoping the enticement of cold, hard cash will help flush him out.
And Thursday, the reward for information leading to his arrest has been increased to $15,000.
The Bureau of Alcohol, Tobacco and Firearms has added another $5,000 to the $10,000 reward announced Wednesday by Sioux City police.
That initial money was offered by United States Marshal Service, Crime Stoppers, and anonymous donations.
21-year-old Jamal Dean is accused of opening fire on the patrol car of Officer Kevin McCormick during a traffic stop for a seatbelt violation on Monday.
Officer McCormick was shot in the forehead, but is expected to fully recover from his wound.
His car was riddled with eight shots from a 22 caliber rifle.
Dean is being charged with attempted murder.
"Dean is dangerous and is a threat to public safety," said Chief Young.
Anyone with information on the whereabouts of Dean should call 712-279-6960.
Dean is considered armed and dangerous and should not be approached by the public.
