(ABC 6 News) – A man is behind bars on multiple child pornography charges in Rochester.

According to the Rochester Police Department (RPD), officers arrested a man in connection with Child Sexual Assault Material (CSAM) crimes after receiving cyber tips from the National Center for Missing and Exploited Children (NCMEC) and the Minnesota Bureau of Criminal Apprehension.

The tips said that the suspect, who was later identified as Gavin Wacker Sullivan, a 30-year-old man from Rochester, was actively possessing and disseminating child pornography.

According to court documents, police received the tip, related to a KIK account with the username “gavin.sullivan507” and a Gmail account later associated with Sullivan, on July 2.

The account allegedly had photos and videos of children between ages 6 and 8 engaging in sexual behavior.

RPD says officers then executed a search warrant and arrested Sullivan in the 600 block of 19 Avenue SW July 11.

Court documents allege that Sullivan answered the door, “then attempted to flee back into the house.”

Police allege that a preview on one of several electronics found in the home shows “many images consistent with CSAM” labeled “One Drive,” “Desktop,” “Old PC Backup,” “Old Computer,” “Funstuff,” and more.

Court documents allege the files depicted children as young as four engaging in sex acts with adults.

Sullivan is scheduled to appear in court again July 24.
