PHOENIX (3TV/CBS 5) - A suspected serial rapist may have been hard to catch because he had never been arrested for sexual assault before.
Isaias Jimenez-Perez is facing 19 felony charges, including kidnapping and sexual assault.

Despite the accusations, police believe he may have committed his first rape only a year ago.
"(Rape) gives them that bold stance to commit another one” said Sgt. Armando Carbajal, Phoenix Police. “It appears that's what happened in this case."
A check of Jimenez-Perez’s criminal past shows only non-violent convictions for things like drunk driving, driving with a suspended license and solicitation of a prostitute.
Those charges only happened in the United States, however.
Jimenez-Perez is originally from Mexico and investigators may soon look into his life there.
As the case against the suspected serial rapist ramps up, there have been questions for Phoenix police as well, including why they didn't they alert the public when two rapes happened in the same area on the same day.
Police told Arizona’s Family it is a matter of when the crimes came to light.
"(It is) date and time of occurrence versus date and time of reporting. Sometimes we get delayed reporting," Sgt. Carabajal said.
Jimenez-Perez is currently at the Maricopa County Jail. He will be back in court at the end of November.
