Slain Massachsuetts police officer laid to rest

HANOVER, Mass. — A Massachusetts police officer who was shot and killed while investigating a car crash last weekend is being laid to rest.

A funeral Mass for Weymouth Sgt. Michael Chesna was held Friday morning at St. Mary of the Sacred Heart in Hanover, followed by a burial at Blue Hill Cemetery in Braintree.

Chesna was killed Sunday by a man who police say threw a rock at the officer and then repeatedly shot him with his own weapon.

The suspect also is charged with killing a 77-year-old bystander, Vera Adams.

On Thursday, thousands of police officers from across the country honored the 42-year-old decorated U.S. Army veteran with a solemn procession.

Chesna, a Hanover resident, leaves behind a wife and two young children.
