AVONDALE, AZ (AZFamily) — A West Valley high school teacher faces child sex charges after police say he was caught soliciting sex with a 15-year-old girl but was actually talking to an undercover agent.

Authorities say 28-year-old Domenik Brewer is one of the cases of child sex trafficking after he was arrested during a sting operation last week.

Court documents say Avondale police conducted an operation with the West Valley Sex Trafficking Task Force.

At that time, a decoy ad was placed on a website known for child sex trafficking and prostitution, police said.

Authorities say the ad depicted a 15-year-old girl and included phrases that suggested she was a child. Investigators say Brewer sent a text message to the number posted on the ad, saying he was 27 years old, to which the tracking agent said he was 15.

After the agent said she was a minor, Brewer said, “Oh wow,” and later said, “I guess I’ll give it a shot,” before asking how much money the girl wanted.

Court documents say Brewer talked about oral sex and expressed interest in “full services.” Brewer then agreed to pay $150 and continued to discuss whether a condom would be used and continued a conversation suggesting he was talking to a teenage girl and a high school student.

Detectives linked the phone number to Brewer and waited for him to arrive after he said he would come in a black Volkswagen. He was arrested after arriving at the agreed meeting place.

After his arrest, Brewer said he coached the Phoenix Suns Youth basketball team and they played in many areas, not just the Footprint Center. He also said a detective is a permanent substitute teacher at West Point High School in Avondale, the documents state.

During the interview, authorities say he admitted he knew she visited a website that would lead him to escort him, knew the girl in the ad was 15 and they agreed to a deal, documents state .

Detectives unlocked his cell phone with permission, showing him the text messages he had with the bait, and later called his wife, telling her he “f**ked” and was arrested for child sex trafficking, telling her that he tried to have sex. with a 15-year-old.

Brewer was found to have $160 on him at the time of his arrest. He has since been jailed on $50,000 cash-only bail.

The Arizona family reached out to the Tolleson Union High School District for comment, but did not immediately hear back.
