Police say a 32-year-old Roswell man who had a months-long sexual affair with a 17-year-old later forced the teen to continue having sex by threatening to out him to his parents, peppering him with text messages and confronting him at work.

But what led to the arrest of Cayden Justin Williams (photos) was a handful of nude photos Williams allegedly took of the teen with his iPhone. The two started having sex in December when the teen was 16, which is the age of consent in Georgia. But state law prohibits taking nude photos of people under the age of 18.

Williams eluded Alpharetta police for weeks, including fleeing from a daycare center where he worked, before finally being arrested on Aug. 26. He remains without bond in the Fulton County Jail, charged with sexual exploitation of a child, obstruction and four counts of identity fraud. WSB first reported Williams' arrest on Friday.

The teen's parents reported the relationship to Alpharetta police on July 9, telling investigators they just learned of the months long ordeal. The teen posted an ad on Craigslist in the fall of 2013 seeking sex with another man and Williams responded, according to police. He told the teen he was 24 and the pair met on Dec. 12 in Williams' Roswell apartment for sex. They performed oral sex on one another and Williams wanted to top him, but the teen refused when the anal sex hurt.

“Williams continued to contact him after the first night and he would meet him and they would engage in sexual acts when they were together,” according to a police report. After several weeks, the teen wanted to end the sexual relationship but Williams refused and then allegedly threatened to out the gay teen to his family.

From the police report:

“Williams told him he would contact his parents and tell them everything. Williams told him and described his mother and fathers residences and also their places of employment. He said, Williams said, he would show them all the pictures he took of him and also place them online if he did not continue to meet with him. [The teen] said he kept seeing Williams in fear of him contacting his parents and also posting his pictures online.”

The two continued to have sex in hotels and public places around Alpharetta, Roswell and north Fulton and during trips to Callaway Gardens, Tennessee and Alabama.

“He continued to perform sexual acts with Williams so that he would not get mad and tell his parents or post the pictures,” according to the incident report.

The aggressive behavior by Williams continued, the teen told police. Williams bailed the teen out of jail when he was arrested in March for speeding and threatened to have the teen “thrown back in jail” if he didn't continue having sex with him.

“He stated he was afraid of Williams because he had threatened to expose his sexuality and the nature of their relationship to [the teen's] parents and friends. He states that Williams has a very aggressive temper and that if he doesn't respond to his text messages immediately he gets very mad at him and starts accusing him of cheating.”

Williams even showed up at the teen's job to yell at him in the parking lot, police said.

Williams flees, leaving behind $48,240 in cash

The teen later showed police where Williams lived and on July 11, police searched his Alpharetta apartment. They seized a flash drive, a cardboard box of cards and photos, and a laptop, though investigators found nothing on the computer to support additional charges. But the collection of photos included six nude images of the teen that Williams snapped with his iPhone.

Williams wasn't in the apartment when police searched it, but played phone tag with detectives for at least four weeks. They told him he faced arrest and needed to surrender; Williams said he had to return to Alabama for a family emergency, according to the incident report.

On Aug. 8, police attempted to arrest Williams after the manager at his apartment complex reported seeing him. That prompted a call from Williams questioning a detective about why police were at the apartment. He eventually hung up on the office but not before being told again that he faced arrest warrants.

More than two weeks later, on Aug. 25, police received a 911 call that Williams was located at an Alpharetta daycare center where he worked. Williams apparently jumped a fence and fled into nearby woods before officers arrived. He eluded a search that included police dogs and witnesses said his sister picked him in her car. But Williams left behind a backpack and vehicle that helped police track him to his sister's apartment in Sandy Springs.

A day later, Sandy Springs police arrested Williams and his brother-in-law, Chucky Ronardo Geter, at his sister's apartment. A search of Williams' vehicle left behind when he fled the day before contained $48,240 in cash and documents police say prompted the four charges of identity fraud.

Williams has at least four Facebook pages under several aliases, including C.J. Williams and Cayden Justin Williams.

In 2005, Williams was arrested and charged with molesting two boys. At the time, the 24-year-old was known as Lordrick Williams and owned daycare center Kidz 1st. After 15 months in jail awaiting trial, a jury in Montgomery, Ala., deliberated less than 40 minutes before finding him not guilty on five counts of first-degree sodomy and two counts of first-degree sexual abuse, according to the Decatur Daily. Williams later sued for defamation and malicious prosecution.

Last September, Williams legally changed his name to Cayden Justin Williams in Fulton County Superior Court.
