Officers raided Prince's home Sept. 19 and confiscated three computers said to contain sexually explicit images of juvenile boys. Police arrested Prince on Sept. 25. About an hour after being booked into jail he posted $10,000 bail and was released.
Prosecutors on Thursday charged Prince in 2nd District Court with five second-degree felonies for sexual exploitation of a minor.
Ruth provided few details about the nine new accusers, though he did say they are all adults now and are cooperating with police.
"They're wanting some resolution to this," he added.
Ruth also said he had "no doubt" there are additional victims, given Prince's decades-long career as a junior high teacher and time as a Boy Scout leader in the South Ogden area.
Prince was employed as a teacher at South Ogden Junior High School from 1979 to 2008.
Prosecutors have had not filed any charges Monday reflecting the new accusations against Prince, though Ruth said more charges could be forthcoming.
Prince tried to kill himself at a Logan home on the day prosecutors charged him, police say. He reportedly slit his wrist and ingested mercury, but was discovered alive about 3 p.m. Thursday. Prince was hospitalized after the suicide attempt.
The incident exposed several police officers and emergency responders to mercury, and the Logan Police station, along with two officers' homes, had to be decontaminated.
Prince is scheduled to make his first appearance in court Wednesday afternoon.
Anyone with information on this case is asked to call the Weber County public dispatch office at 801-629-8221 and ask to speak to a South Ogden police officer. Police have said they will protect the identities of any potential victims.
