A South Thomaston man arrested in January for the summer robbery of Jensen's Pharmacy pleaded not guilty to charges Feb. 27.

Michael Willis, 29, represented by Damariscotta-based attorney Patrick Parson, was arraigned in Knox County Superior Court Wednesday.

Willis faces four charges including class B robbery, aggravated trafficking in schedule W drugs, stealing drugs, and unlawful possession of drugs.

The robbery at Jensen's Pharmacy on Camden Street occurred the afternoon of July 31, when a male passed a note to a pharmacist demanding drugs, according to police.

According to documents filed in Knox County courts, the note requested "oxys", or oxycodone pills in 15 and 30 milligram tablets. At the bottom of the note, the word "guns" was written.

The cost to replace the drugs was $139, according to court documents.

Willis was implicated as a suspect from information garnered from cellphone records and DNA testing, according to Rockland Police Department Detective Russ Thompson.

Cellphone records, obtained through a search warrant, showed two calls were made near the pharmacy on Willis' phone shortly before the robbery.

A jacket and hat found near the crime scene, along with DNA samples from Willis, were sent to the Maine State Police Crime Lab for comparison. The samples were a match, according to court documents.

On Jan. 9, Willis was released on $3,000 cash bail.
