AUBURN – A man accused of selling narcotics to high school students paid a fine Thursday and was ordered to pay drug agents for part of the cost of their investigation.

Scott Tiner, 20, was ordered to pay a $500 fine and $150 restitution after pleading guilty to a charge of trafficking in marijuana.Tiner was arrested in May after drug agents raided his home on Park Avenue in Auburn. Police accused him of selling marijuana and Ecstasy to local youths for at least a year.

According to a police affidavit released at the time of his arrest, drug agents began investigating Tiner after receiving a call from one mother who found Ecstasy in her 14-year-old daughter’s room and a local father who knew about a situation in which another young girl went to the hospital after taking Ecstasy.

Ecstasy is a synthetic, psychoactive drug chemically similar to the stimulant methamphetamine and the hallucinogen mescaline, according to the National Institute on Drug Abuse.

The girl who went to the hospital was interviewed by police in September 2003. According to the affidavit, she admitted that Tiner was her boyfriend and that they had a sexual relationship.

She also said that Tiner had been giving Ecstasy to her and her friend, who was the same girl whose mother called police earlier, according to the affidavit.

Police continued to investigate Tiner and eventually sent a confidential informant to his home to buy drugs. Equipped with an electronic listening device, the informant bought a half-ounce of marijuana on April 7 and another half-ounce in early May, the affidavit says.

Investigators said they confiscated scales, drug paraphernalia and $750 in drug money from Tiner’s home May 24.

He was originally charged with two counts of trafficking marijuana. As part of a plea arrangement, Tiner pleaded guilty to one count. The $150 restitution was ordered to repay the Maine Drug Enforcement Agency for the money it used in undercover buys as they investigated the case.
