AUGUSTA — A man who robbed a Winthrop Rite Aid in December 2011 is back behind bars on a new drug trafficking conviction.

Anthony R. Caballes-Mabe, 22, known to police as “Taco,” was sentenced Monday in a hearing at the Capital Judicial Center to three years in prison for unlawful trafficking in cocaine. The offense occurred April 8, 2015, in Augusta, according to court records.

The sentence is to run concurrently with a four-year probation violation.

Caballes-Mabe had pleaded guilty Sept. 22 to the new charge. He also was fined $400.

He was convicted previously of a Dec. 7, 2011, robbery of the Winthrop pharmacy and of stealing oxycodone and received a split sentence of three years to serve initially and an additional five years suspended. He was placed on probation for three years.

Police investigating that robbery found white-rimmed sunglasses that had been worn by the robber — something customers who witnessed the robbery described as odd because it was dark and rainy — and pill bottles found discarded between the Rite Aid store and Metcalf Road. Not long afterward, an anonymous caller told Winthrop police that Caballes-Mabe had committed the robbery, according to a court affidavit by Winthrop Detective Peter A. Struck.

Caballes-Mabe, who had previous addresses in Randolph and Augusta, provided an address of Killeen, Texas, on the court documents that he signed after the sentencing Monday.

He also was convicted in 2012 in Kennebec County Superior Court of unlawful possession of scheduled drugs.

Other people were sentenced this week during separate hearings at the Capital Judicial Center:

• Randolph N. Murray, 53, of Athens, two counts each of violating a protective order and violating condition of release July 11 to 14, 2014, in Augusta; 180-day jail sentence, all but 48 hours suspended, one year of probation.

• Katina Paquette, 42, of South China, theft by unauthorized taking or transfer Sept. 21, 2014, in Augusta; two-year jail sentence, all suspended, two years of probation.
