The Anchorage Police Department (APD) is concerned a man they arrested for crimes against children charges could have additional victims.

On Sept. 1 APD’s Crime’s Against Children Unit received reports that 21-year-old Tyler Rifley had inappropriate contact with “multiple teenage boys,” who were between 12 and 14 years old, police said in a dispatch.

“On August 31, 2016 a mother reported to police that her 13-year-old son had been associating with Rifley. It was reported that her son and other minors had hung out with Rifley on multiple occasions and he had asked them for sexual favors,” APD wrote.

APD said on one occasion Rifley began showing pornography to one of the teens and asked a teen for sexual contact.

Rifley is charged with distribution of indecent material to minors, plus contributing to the delinquency of a minor.

His bail was set at $15,000. He was taken to the Anchorage Correctional Complex.

APD said there is “concern” that Rifley could have had other victims.

Anyone who’d like to come forward or who has more information is being urged to call detective James Williams at 907-729-7869.
