A 36-year-old Portland man will spend seven years in prison for selling cocaine to a police drug informant twice last year in Rockland.

Kaihlil Nigro was sentenced March 26 in Knox County Superior Court to 10 years in prison with all but seven years suspended for two counts of aggravated trafficking in cocaine. He will then be on probation for four years.

Nigro was found guilty Dec. 15 after a two-day jury trial in Rockland.

He was on probation for a December 2008 conviction for felony cocaine possession from Cumberland County when he was arrested last August in Rockland. His probation was revoked upon his conviction.

Testimony showed that in August 2009, Nigro traveled from Portland to the Rockland area to sell cocaine. Twice on Aug. 25, he sold cocaine to a confidential informant working with the Maine Drug Enforcement Agency.

He was one of three people arrested. Drugs were seized at an Eliza Steele Drive residence and a local brother and sister were arrested.

Law enforcement officers from the Rockland Police Department, Maine State Police, Knox County Sheriff’s Office and Maine Drug Enforcement Agency executed a search warrant in Rockland on Sept. 1 and found Nigro in possession of 47.8 grams (1.69 ounces) of cocaine. Agents located the cocaine in a safe belonging to Nigro. The 17 one gram packages and the 12 three gram packages found in Nigro’s possession had a street value of approximately $5,300.

Maine Attorney General Janet Mills applauded the cooperative efforts of the law enforcement agencies involved in the investigation of this case.

“Law enforcement agencies working together to share information and resources, as they have in this case, is essential to the successful identification and prosecution of drug traffickers like Mr. Nigro,” Mills said in a news release. “We are pleased that he has now been held accountable for his crimes.”

Mills also thanked Assistant Attorney General Lisa Bogue for her successful efforts in prosecuting this case. Bogue is a drug task force attorney within the criminal division of the Attorney General’s Office.
