The statewide number of homicides in Maine decreased slightly in 2020 compared to recent years, with 20 reported cases of murder or manslaughter by year’s end, the Maine State Police said.

Six of those deaths involved domestic violence, including an alleged double murder in Waldo in October, according to an annual report released Friday.

Fewer homicides took place in 2020 than in any year since 2012 – with the exception of 2018, which saw only 18.

Overall, crime has steadily been falling across Maine for eight years, though some kinds of violent crime – such as rape – have increased. Reported rapes rose by 15 percent in 2019, the last year for which complete crime statistics are available. Some of that increase may be attributable to victims reporting crimes at a higher rate, law enforcement officials say.
