FORT SMITH - Thousands of law enforcement officers from across the region and across the country on Tuesday paid their final respect to Sebastian County Deputy Cpl. Bill Cooper who was killed Aug. 10 in an early morning shootout. More than 3,000 people crowded into the Fort Smith Convention Center, including Arkansas Gov. Asa Hutchinson, Sen. John Boozman and state Attorney General Leslie Rutledge. Sebastian County Sheriff Bill Hollenbeck told the people gathered that Cooper was a law enforcement officer who could be counted on to "stand the gap," that is, to face any battle with courage and integrity and always to show loyalty to fellow officers, "I want our community to know about the amount of sacrifices that our law enforcement and first responders give every single day," Hollenbeck said. "I am amazed by the professionalism and strength and self-control exercised daily by law enforcement officers throughout our land." An estimated 3,300 people, most wearing blue to show support for law enforcement, green to support the Sebastian County Sheriff's Office and black to represent mourning, attended the funeral service, said Jeremy Richey, of the Convention Center staff. Those who attended listened to speakers including Hutchinson, Hollenbeck, Lt. Philip Pevehouse, and pastor Allen Tedford, the former Sheriff's Office chaplain. Residents in the community lined Rogers Avenue to honor Cooper while in route to final burial place. The procession lasted more than one hour, as more than 650 patrol cars, nearly 100 first-repsonder vehicles including firefighters and paramedics, as well as hundreds of bikers and some community members lined up, and slowly progressed down the road. "I am extremely proud of our department in the way that we've handled this horrible situation. I am also extremely proud of other law enforcement agencies... for the assistance they provided... that assistance has been remarkable," Hollenbeck added. Cooper is one of 38 law enforcement personnel in the nation who died while serving their community during 2016. "As a nation, it's a time for reflection, as a state, it's a time of gratitude for those who serve and protect, as a law enforcement family, it's a time of mourning... . I had to make the difficult call when the alarm sounded, 'Officer down,'" Hutchinson said. "One thing I learned from this experience is there's not a greater sense of unity, of loyalty and family than those who are called to serve and protect." Hutchinson added, "... Bill Cooper was a family man with a loving wife and son," Hutchinson said. "He was a friend to those who knew him. He was not particular of who he served because he believed that he served all in need. He responded to every call." During the funeral, Pevehouse said, "We will miss his smile. We will have to get used to a life without his positive attitude and his service, which is still speaking even though he has passed from this life to the next ... . Cpl. Cooper left us a legacy of a warrior." Sebastian County Prosecuting Attorney Daniel Shue attended and said, "Corporal Bill Cooper was an outstanding law enforcement officer and a very kind, decent man. He was a peace officer in almost every sense of the term and my entire office mourns his passing." Thirteen deputies from each Washington County and Crawford County Sheriff's Offices were sent to the Sebastian County Detention Center to work so that Cooper's co-workers could attend his funeral, a deputy said. "Our honor guard and several other WCSO personnel attended the funeral. We assisted and attended to give support to our brothers and sisters at the Sheriff's Office and to honor Deputy Cooper, who gave his life to protect his community and to show support for his family, who have lost so much," said spokesperson Kelly Cantrell for the Washington County Sheriff's Office. Moutainburg Police Department Chief Vincent Clamser and Logan County Sheriff Boyd D. Hicks were among the thousands in attendance mourning. "I was moved by the tremendous show of support by the community where Bill served. It's our turn to step up and fill the gap," Clamser said. Hicks said, "Deputy Bill Cooper was my friend of 25 years. (He was) a fine husband, father, deputy and friend who we can not replace." Many from Fayetteville Police Department were in attendance. "Law enforcement as a whole is like a family. We wanted to be there to support our brothers and sisters in Sebastian County during their time of loss," said Sgt. Craig Stout with the Fayetteville Police Department. Sgt. Daniel Grubbs with the Fort Smith Police Department also said law enforcement is a family. "If you attended today's funeral honoring Cpl. Bill Cooper, you now understand the term 'family' when spoken in the law enforcement community," he said. "An army of blue from across the nation attended to pay respects. River valley law enforcement are still mending broken hearts over last the tragedy last Wednesday. We attended the celebration of Cooper's life today and we didn't say goodbye, we said see you later. Please keep Corporal Cooper's wife, Ruth, his family and his co-workers in your thoughts and prayers."
