Forensic computer analysis explains a near three year gap between the start of a sex offense investigation and the arrest of the suspect. Lake Havasu City resident Dillon Papst, 24, was arrested May 26 and jailed for sexual abuse, luring a minor for sexual exploitation and sexual conduct with a minor.

The investigation began in August, 2014 when a Mohave County health department employee summoned police. Police reports indicated that a 16 year-old girl seeking birth control indicated on a medical/sexual history survey form that she had been a victim of forced sexual activity.

The teen reportedly told an investigator that Papst, her brother’s friend, repeatedly sexually abused her between the ages of 7 and 12.

Police sergeant Tom Gray said the case stalled when a department expert was not able to access the suspect’s computer system. He said the equipment went to a state lab where a forensics expert this year was able to gain access and retrieve incriminating videos and other evidence.

The discovery led to the arrest and jailing of Papst.
