PAWTUCKET — A stolen lottery ticket turned out to be the lucky break Pawtucket police needed to catch the suspect in a Cottage Street convenience store robbery.

According to police, Crystal Giguere, 24, of 156 Broadway, Pawtucket, confessed to the March 22 robbery at the Silver Mart that resulted in a minor laceration to the ear of a female clerk. Police were reportedly able to link Giguere to the incident after she had her mother cash a winning $10 lottery ticket that was among a dozen she had taken from the store that night.
Police said that on the night of the robbery, Giguere had come into the Silver Mart and demanded cash from the store clerk, identified as 63-year-old Joyce Campbell. Giguere and Campbell struggled, police say, and in the course of the fight, Campbell’s ear was cut by a knife that Giguere allegedly had in her possession.
Giguere fled with about $100 cash and 12 lottery tickets, police said. She had dropped the knife, which police recovered.
Police said that when Giguere later discovered that she had won $10 with one of the stolen tickets, she mailed it to her mother in Woonsocket, asking her to cash it for her. When the mother tried to cash the ticket at a local store, a clerk discovered that the ticket was stolen and alerted state lottery officials, police said. The lottery agents contacted Pawtucket police, and further investigation lead them to Giguere, police said.
Giguere was arraigned on Thursday in Sixth District Court in Providence on charges of armed robbery and assault of a person over 60. She was held at the ACI pending a bail hearing on April 16, according to police.
