Blue Lives Matter rally held for murdered cop; police investigate ominous image day of cop's wake

Natick, Massachussetts, saw a Blue Lives Matter rally held in honor of a murdered police officer on Saturday — but elsewhere in the region, police investigated a sign that was spray-painted with the demand, "Kill cops."

The spray-painting reportedly occurred on Thursday, the day of the officer's wake.

What are the details of the rally?

According to WBZ-TV, Saturday's rally was held in Natick's Town Common.

The rally was held to honor Weymouth Police Sgt. Michael Chesna, who was murdered last week while he investigated a car accident.

A suspect reportedly threw a large rock at the officer's head and then repeatedly — and fatally — shot Chesna, 42, with his own service weapon.

Natick resident Jim Hannon was the organizer of the rally, and according to the station, residents and police officers  showed up to pay tribute to Chesna and bring awareness to his vicious murder.

"After hearing about Officer Chesna’s death, there was a sense of sadness and it turned to anger," Hannon told WBZ.

"The police community is so tight and what ends up happening is, one officer dies, they all feel it,” Hannon added.

According to WBZ, the rally was not intended to make a political statement, but to highlight the need for awareness that police are often under attack.

What are the details of the 'Kill cops' sign?

On the same day that Chesna's wake was held — which thousands of police officers attended — police investigated a sign in Southbridge, Massachusetts, that read "Kill cops."

According to WBZ, the threatening message was spray-painted on a sign at a local soccer field.

The station reported that the Southbridge Police Department do not believe that there is an "immediate threat" to police officers, and the sign has since been removed.
