Michael Harris, 30, was sentenced to 13 years in prison Friday for a nine-town robbery spree that lasted four months.

The sentences from several jurisdictions will run concurrent with one another.

Felony charges against Harris included 13 counts of first-degree robbery with a firearm, from Nov. 20, 2016, to Feb. 1, 2017.

He robbed businesses along a corridor of routes 8 and 84, Milford State’s Attorney Kevin D. Lawlor said Friday. Miller hit Derby, Middlebury, Milford, Naugatuck, Shelton, Waterbury, Southington, Torrington and Winchester.

After an investigation, Naugatuck police got the first arrest warrants.

“We caught him,” Naugatuck Deputy Chief Joshua Bernegger said Friday.

The robberies had several things in common: a man seen wearing a gray hoodie, carrying a large handgun, and driving a green car, possibly a 2009 or 2010 Toyota Carolla four-door with Connecticut plates. Also, he was wearing blue Nike sneakers, Bernegger said.

• In Superior Court, Milford, Judge Frank Iannotti sent Harris to prison for 15 years, with eight to serve, and five years of probation. Harris, who did not appear in court, was sentenced for first-degree robbery, including three cases of threatening with a firearm. Lawlor said the robberies netted Harris $300-$3,000.

• In Superior Court, New Britain, he was sentenced without an appearance, to 10 years.

• In Litchfield Superior Court, Torrington, Harris appeared and received a total of 17 years in prison, suspended after 10 years, minimum mandatory and five years probation.

• In Waterbury Superior Court, he appeared and was sentenced to 13 years in prison.

Harris has been held since February 2017 at Northern Correctional Institution, Somers, in lieu of $1.37 million bail.
