PORTLAND — An Auburn man charged with selling more than 26 grams of crack cocaine over three meetings with an undercover buyer had his first appearance in federal court Wednesday.

Pierre Calhoun, 39, was in U.S. District Court, clad in a tan jail suit and bright orange canvas shoes on his feet.

Calhoun waived his right to challenge his detention, which prosecutors had requested.

He faces a charge of distribution and possession with intent to distribute controlled substances, a felony punishable by up to 20 years in prison and up to a $1 million fine.

A probable cause hearing was scheduled for next week.

On Jan. 24, Calhoun sold one gram of crack cocaine to a U.S. Drug Enforcement Administration confidential source who met with Calhoun and paid him $100, according to an affidavit sworn by Special Agent Robert Brooks.

On May 16, the confidential source paid Calhoun $800 for 10.4 grams of crack cocaine.

On June 13, the confidential source met with Calhoun and paid him $1,000 for 14.7 grams of crack cocaine, according to Brooks.

The confidential source showed Brooks the texts exchanged between him and Calhoun before each of the drug buys, which took place in Lewiston.

Each time, the confidential source was equipped with recorded cash as well as audio and video electronics aimed at capturing the deals digitally.

Agents were able to monitor the transactions electronically from nearby locations, Brooks wrote.

The drugs were tested each time and confirmed as crack cocaine.
