Augusta police have arrested two people on warrants after an employee at Walgreens in Augusta recognized one suspect from news reports about thefts at Walmart in Farmington case and alerted police Friday afternoon.

Thomas Mulkern, 29, and Angelia M. Carrigan, 37, who were both wanted on arrest warrants, are being held at the Kennebec County jail.

Augusta police arrested them around 4:30 p.m. Friday after a Walgreens employee notified police that the pair had stopped in and were expected to return, according to Sgt. Christian Behr. Police stopped their vehicle on Winthrop Street near Mount Hope Cemetery, Behr said. The two live in Jay, according to the Augusta police arrest record.

Farmington police announced Thursday they were searching for Thomas Mulkern and Angelina Carrigan-Sounier, 25, in connection to recent thefts at Walmart in Farmington but did not say what the two are suspected of taking.

Augusta police, when asked if Carrigan and Carrigan-Sounier are the same person, said that Carrigan is known to use a number of aliases.

Farmington police spokesmen were unavailable for comment Saturday evening.

Police said the warrants for Carrigan’s arrest were related to unpaid fines and theft charges originating in an Augusta court.

Mulkern previously was a key witness for the prosecution in the high-profile arson trial of Raymond Bellavance Jr., who burned down the Grand View Topless Coffee Shop in Vassalboro in 2009.

Mulkern was granted immunity for testifying that he had helped carry gasoline cans and watched Bellavance pour out the gas and then light the fire, which forced the owner and six family members, including two infants, to flee from their rooms at the former motel.
