The boyfriend of a missing Arizona teenager has refused to take a polygraph test, Phoenix cops say.

Police picked up Jon Christopher Clark, 23, at a hotel on Monday and brought him to the police station for questioning, where he refused to take the lie detector test because he didn't want 'an interpretation for my feelings'.

His girlfriend Kiera Bergman, 19, has been missing for two weeks.

She disappeared on August 4 in Phoenix, just a short time after leaving her hometown of San Diego to move in with Clark.

Clark has repeatedly denied having anything to do with her disappearance and police say he's not considered a suspect or person of interest in the case. 

'I didn’t want to do anything that would give the indication I was hiding anything but also didn’t want anything on the record that would have them say I was doing anything or had any part in this,' Clark said to the Huffington Post. 

'I told them I would not like a lie detector test because, one, they are not admissible in court, and two, whatever you guys gather from that is basically your interpretation on my feelings.

'So I didn’t want [investigators] to pretty much gather [their] conclusions off of something that is not guaranteed,' he added. 

When cops arrived to talk he felt cornered as he was 'abruptly surrounded by 20 tactical officers'.

'I just really felt like they were treating me like a suspect,' he said.

'They handcuffed me, put me in back of a car and, when we got to the interview room, [they] handcuffed me to a table the entire time,' he added.  

That same day police had a warrant to search his car, where they discovered material relating to identity theft and forgery. 

On Friday Clark was arrested for the alleged forgery crimes unrelated to the disappearance of his girlfriend, according to ABC.

He was charged with 22 counts of aggravated identity theft and two counts of forgery, according to the Phoenix Police Department. 

He says they got into a fight before she disappeared without a trace on Saturday August 4

Her roommate said the last thing she heard from Bergman was that she was going to meet with a man she had met at a store, something that was unlike the 19-year-old's normal character

Clark and Bergman have been dating since December. She moved to Phoenix in March to be with him.

Her father described it as a 'on-again, off-again relationship.' 

Bergman was last seen leaving her job at a furniture store on August 4 'noticeably' upset according to her co-worker. 

Clark picked her up from work and took her back to the apartment. He said they got into an argument over finances. 

He added Bergman mistakenly though Clark was leaving Phoenix, where the pair had just moved together from San Diego. 

He last saw her when she walked out of the house around 1pm and she wasn't heard from since. 

'When she left there was no immediate concern because we have had arguments in past where either me or her have left for an hour or a couple at a time to go clear our head. I didn’t really find it unusual until she wasn’t in contact with me,' he added. 

She had left her wallet, purse, and car at the apartment. 

She has been missing for two weeks. Police have not named Clark as a suspect of person of interest in the case despite the questioning on Monday

Her roommate Destiny Hall-Chand, who shared the apartment with the couple, said that Bergman texted her saying she was going out with a man she had recently met.  

'She was saying that she was going to go out with some guy that she met at the store a couple days ago, which is something that's not like her, I mean, that's not something that she would do,' Destiny Hall-Chand told CBS affiliate KPHO-TV.

'I don't know. I don't know what to think, I don't know what to believe, I don't know. It's just, I know there's something wrong. I'm just hoping she'll come home and everything will be okay,' Hall-Chand added.   

Kiersten Bragg (R), Kiera's mother, said she received a phone call from one of her daughter's friends soon after she vanished

'They served a search warrant on my phone, car, the place I was staying at and talked to all my friends and family. DNA was one of the stipulations of the court order, so they took my DNA ― did swabs, all kinds of fingerprints, my wrists, hands, everything ― and took numerous pictures of me and my tattoos,' Clark said. 

He added that he fully cooperated with police save for the polygraph test. 

On Saturday August 12 a vigil was held for Bergman as the search for the 19-year-old missing for two weeks continues. 

Her mother Kiersten Bragg said that she's been overwhelmed by the amount of support the community has provided during a stressful time. 

'We are just being flooded with messages and people telling us that they're praying for us and praying that she comes home safe,' Bragg said.   

'They're out there sharing and they're messaging me and telling me they're praying and I'm just so thankful for all those people,' she added.

'You have my heart, so come home,' Chris Bragg, Kiera's father, said. 

A GoFundMe page has been setup by a member of Bergman's family to help fund the search for Bergman.
