There were fewer serious crimes reported by Rockland police, Thomaston police and the Knox County Sheriff’s Office in 2021 compared to 2020. Camden and Rockport reported increases.

That is the information included in the 2021 Crime in Maine report issued Thursday, Dec. 22 by the Maine Department of Public Safety.

The crime statistics are categorized differently than in past years but comparisons can be made to prior years. The state has compiled uniform crime reports since 1973.


Rockland reported 89 crimes which had in past years been considered the more serious index offenses. That is down from 129 in 2020.

These offenses include murder, rape, robbery, arson, aggravated assaults, burglary, thefts, and stolen motor vehicles. The 2021 crime statistics include additional categories.

Rockland reported no murders, three rapes, no robberies, no arsons, three aggravated assaults, three burglaries, and 77 thefts (shoplifting, thefts from buildings, and theft from motor vehicles).

As late as 2010, Rockland had 427 index crimes. That dropped substantially after Walmart moved to Thomaston, eliminating many of the shoplifting offenses. Rockland’s crime rate peaked in 1980 when 749 of the index offenses were reported.

Rockland also reported 18 instances of vandalism in 2021 and 39 of drug offenses during 2021. These offenses were not included in what had been known as the serious index crimes.

The Rockland department made 165 arrests during 2021 of which 46 were for operating under the influence.


Thomaston reported 44 of what had previously been known as index crimes during 2021. This is down from 94 in 2020, and 65 in 2019. Thomaston had 44 reported index crimes in 2018.

In 2021, Thomaston reported one aggravated assault, one burglary, 40 thefts, and two stolen motor vehicles.

Thomaston reported six vandalism incidents and one drug offense during 2021.

Thomaston police made 19 arrests of which five were for OUI.


Camden reported 25 index offenses 2021. This compares to 12 in 2020, three in 2019, 14 in 2018, and 30 in 2017.

In 2021, Camden reported one sexual assault, five burglaries, 18 thefts, and one stolen motor vehicle.

Knox County Sheriff’s Office

The Knox County Sheriff’s Office, which largely covers the communities with no municipal department, reported 118 offenses formerly known as index crimes during 2021.

This is down from 160 index crimes during 2020. This is down from 162 in 2019, 163 in 2018, 184 in 2017, and 186 in 2016.

Knox County reported four aggravated assaults, nine burglaries, 101 thefts, and four stolen vehicles.

The county department also reported 55 instances of vandalism and 12 drug offenses during 2021.

Knox County officers made 164 arrests of which 14 were for OUI.

The Maine Department of Public Safety stated that “while some of the category names remain the same from summary UCR, what is collected under the category name, may now be different. For example, summary UCR had the single category of theft. Now in incident-based reporting, there is no single category of Theft. Instead, IBR has multiple categories, such as purse snatching, shoplifting and theft from a motor vehicle. While these categories provide more detailed insight into the type of theft that occurred, it makes it very difficult to compare against summary UCR data, as all IBR theft categories would need to be added together to come up with an approximation of the old summary UCR theft category.”
