WATERTOWN — Two 18-year-olds, one of whom pleaded guilty to an armed robbery in Cape Vincent in January, are accused of stealing a vehicle from a Brown Road residence Monday morning. Rafael E. Cabrera-Jones and Jesse A. Blake each were charged with stealing a 2006 GMC Envoy from 22026 Brown Road in the town of Pamelia at about 5:30 a.m. Their addresses are listed as Room 124 and Room 118, respectively, at the Rainbow Motel, 22480 Route 12. Both were charged with third-degree grand larceny, a class D felony. They were arraigned in Brownville Town Court and sent to the Metro-Jefferson Public Safety Building on $30,000 cash bail. The investigation continues and additional charges against the two are pending, police said. State police were assisted by investigators from the Jefferson County district attorney’s office and the Jefferson County Department of Social Services. Mr. Cabrera-Jones pleaded guilty May 5 to second-degree robbery after he was charged with holding up two Cape Vincent businesses in January. Police said he entered Cape Dairy, 112 Broadway St., wearing a ski mask and displaying what turned out to be a starter pistol and demanded cash. Following the first robbery, police said, Mr. Cabrera-Jones went to the Cape Vincent Liquor Store, 154 Lee St., again showing the weapon and demanding money. Police said he made off with $900, a bottle of vodka and a pack of cigarettes between the two businesses before police followed his footprints back to an apartment at 544 E. Broadway St., where he was arrested. For the guilty plea, he was sentenced to an unspecified amount of time served at the Metro-Jefferson Public Safety Building and five years’ probation. He was granted youthful offender status in the robbery case.
