BREWER, Maine — A police investigation into drug trafficking at a Wilson Street hotel last week resulted in the arrest of three people — one for aggravated felony trafficking — after each was found with drugs, Capt. Jason Moffitt said Monday.

Four officers raided the hotel room of Elizabeth Mikotowicz at around 9 p.m. July 13 after receiving “information that an individual was dealing drugs: bath salts and cocaine,” the police captain said.

While standing outside the hotel room, police reportedly heard people inside talking about being armed and “they could also be heard talking about ‘monkey dust,’ the street term for bath salts,” Moffitt said.

“Bath salts” are a synthetic drug that became illegal in Maine at the beginning of July and usually contain mephedrone or Methylenedioxypyrovalerone, also known as MDPV. Police, doctors and emergency responders have reported signs of paranoia, hallucinations, convulsions and psychotic behavior in users of the drug.

Police searched the occupants of the room and found Mikotowicz and Benjamin Sprague, 27, both listed as transients, and Jennifer Beeler, 20, of Enfield with drugs, according to Moffitt.

He said Mikotowicz’s purse held 13 diverted prescription oxycodone pills and a small container of cocaine, and that police found hypodermic needles in the hotel room as well.

Mikotowicz, 24, was charged with felony aggravated trafficking in scheduled drugs “due to the amount they found and they’re within 1,000 feet of a school,” the police captain said.

Mikotowicz also was charged with unlawful possession of cocaine and sale and use of drug paraphernalia.

A plastic baggie with a “chunky white power” was found on Sprague, who told police he had monkey dusk in his sock, Moffitt said. Police also found a folded-up piece of tinfoil in his sock that contained drugs. Both substances tested positive for cocaine.

“We’re hearing reports that they are mixing the two drugs,” Moffitt said of cocaine and monkey dust.

Sprague was charged with illegal possession of cocaine and unlawful possession of synthetic hallucinogenic drugs for the bath salts.

While Beeler was dumping out her purse, Cpl. Levi Sewall noticed she was concealing a small container in her hand, which held diverted Xanax, an anti-anxiety drug, and she was charged with illegal possession.

Police arrested Mikotowicz, Beeler and Sprague and took all three to the Penobscot County Jail. Mikotowicz could go to prison for up to 30 years and be fined $30,000 convicted of felony drug trafficking in scheduled drugs.
