ALAMOGORDO, N.M. — Police have launched an investigation after a memorial honoring fallen law enforcement officers in southern New Mexico was vandalized.

The Alamogordo Daily News reports that Alamogordo police say the vandals sometime between Monday and Tuesday caused up to $3,000 in damages to the memorial that contains plaques honoring 10 officers.

Rocky Galassini, who heads a local committee on police appreciation, says all of the plaques were destroyed and need to be replaced. She said it’s unimaginable that someone would destroy a memorial honoring “people who have given the ultimate sacrifice.”

Police and local organizations are offering rewards for information leading to arrests and indictments of the people responsible for the vandalism.
