SPRINGFIELD, Mass.

Associated Press/Steve Helber SPRINGFIELD, Massachusetts — A Massachusetts police department is investigating a Facebook comment by an officer who wrote "Hahahaha love this" in response to a story about a car crashing into counterprotesters at a white supremacist rally in Charlottesville, Virginia, killing one person and injuring at least 19 others.

Springfield Police Commissioner John Barbieri said he received a complaint about the comment Sunday and opened an internal investigation.

Officer Conrad Lariviere wrote in response to the violence: "Hahahaha love this, maybe people shouldn't block road ways."

In a Facebook interview with Masslive.com, Lariviere said he's a "good man who made a stupid comment."

"Never would I want someone to get murdered," he told MassLive. "I am not a racist and don't believe in what any of those protesters are doing."

Democratic Mayor Domenic Sarno released a statement on Lariviere's comments Sunday night.

"I just got done issuing a statement this morning on how upsetting the tragic incidents were in Charlottesville, Virginia and one of our own officers does this? Unbelievable! There is no place for this in our society, let alone from a Springfield police officer," Sarno said. "I stand by and commend Commissioner John Barbieri's steps for a thorough internal investigation and review by our Community Police Hearing Board to pursue the appropriate discipline against said officer."

An Ohio man is charged with second-degree murder and other counts over the crash.
