Londonderry police released a statement about the robbery on Wednesday morning and with the help of the public, officers and detectives were able to identify and locate a suspect, Malloy said. Skillin was arrested by Londonderry police while in the custody of the Manchester Police Department.

Skillin was held without bail and was scheduled to be arraigned on Thursday. Malloy said the investigation remained “ongoing.”

Skillin’s criminal history dates back more than two decades, according to superior court records.

In October and December 2002, he was involved in four different robberies in Manchester.

In March 2013, Skillin was accused of felon in possession of a dangerous weapon and criminal threatening in Derry as well as armed robbery, armed robbery-conspiracy, two unarmed robbery, robbery, and two robbery conspiracy charges in Manchester connected to two separate incidents.

A jury trial was held in the second Manchester case in February 2014, and on the armed robbery charges, he was found not guilty. The jury found him guilty on the other two counts. In May 2014, he was sentenced to three and a half to seven year sentences, served consecutively, with 399 days of time served credit. He was required to pay $895 in restitution. Two years of the minimum sentence was suspended for 10 years. About a month later, Skillin pleaded guilty to felon in possession and criminal threatening, and received two three-and-a-half to seven-year sentences, with one of the sentences suspended for 10 years and two years probation.

Skillin was also charged with drug possession after an incident in Berlin in July 2015. In January 2017, he pleaded guilty to the charge and received a one-to-three-year sentence, with six months suspended and a $434 fine suspended for three years.

Skillin was awarded work release in January 2022.
