PCSO - Michael Kos


FLORENCE — California authorities had been looking for Michael Kos, a dangerous sex offender, since 2011.

On Feb. 13 the Pinal County Sheriff's Office arrested him for trading sexually explicit photographs of minors online.

On Jan. 16 a cyber tip was received from the National Center for Missing and Exploited Children indicating that two people had attempted to trade a sexually suggestive image of children on social media.

“The image, part of a video depicting a 10-year-old male being sexually exploited, was sent by a subject identified as Mike,” a PCSO probable cause statement reads.

Investigators identified the suspect as Kos, a 36-year-old resident of Scottsdale. Further investigation also determined Kos received nude images of a 17-year-old male.

“Mike Kos was located at his residence, and during interview under Miranda, Mike admitted to the communications, receiving video of the 10-year-old from a subject in California and receiving the images of the 17-year-old. He also indicated that he had other images and videos of the sexual exploitation and abuse of children,” the probable cause statement reads.

Kos is also the suspect on a 2011 warrant from California for prior possession of child pornography.

Kos was arrested and booked into the Pinal County Adult Detention Center for two counts of sexual exploitation of a minor and is held on a $250,000 secured bond.
