The ultimate sacrifice of 27 law enforcement officers in Westmoreland County was recognized Thursday by their peers, families and friends. For Rosemarie Reed, it was especially welcome. "This means a lot to me,” she said. "Just knowing the fact that my husband is being recognized for his service.” St. Clair Township police Officer Lloyd Reed Jr., 54, was fatally shot while responding to a domestic violence call on Nov. 28, 2015, in New Florence. Rosemarie Reed, of Holsopple, Somerset County, said she hopes the Police Officers Memorial Service held at St. Clair Park in Greensburg becomes an annual event. That is the intent of District Attorney Nicole Ziccarelli, whose office planned the service attended by a couple hundred police officers, county officials and employees, and others. Families of the 27 fallen officers and members of their departments placed white carnations in a basket as the names were read by Chief Detective Ron Zona. There were prayers, songs and a state police helicopter flyover under a hot sun. The event coincided with National Police Week, which was established in 1962, according to the National Law Enforcement Officers Memorial Fund. "We ask so much of these men and women, from ensuring public safety, to solving domestic violence incidents, substance abuse issues and mental health challenges,” Ziccarelli said. "Our officers, troopers and deputies always rise to the challenge and demonstrate courage and dedication.” It was important to remember the legacies of the 27 officers killed in Westmoreland County since 1900, she said. "They served and sacrificed for a purpose far greater than themselves and exemplified the true definition of a hero,” she said. State police Cpl. Jonathan Lindsay agreed. Four troopers and a state police private were honored during the ceremony. "An event like this is needed to remember and celebrate those we have lost, yet never forgotten,” he said. Murrysville police Chief Thomas Seefeld expressed appreciation for community members who show support for police. He encouraged fellow law enforcement officers to remember their sense of mission and purpose and strive to make a difference in their communities.
