TULSA, Oklahoma - Officers and community members gathered to remember five Oklahoma law enforcement members who made the ultimate sacrifice.

The memorial took place on National Peace Officers Memorial Day, which also was the start of National Police Week.

Deputy Sean Cookson died late February when he and his wife, Cassandra - also a police officer - were on their way to law enforcement training when their vehicle was involved in a wreck.

"I wish Sean could be here to see everybody, he was super proud to be a Deputy of Craig County," Cassandra said.

Monday night, Cookson and four others who died in the line of duty since January were remembered.

"Those lives were not in vain,” Rogers County Sheriff Scott Walton said. “Police officers once again take that oath, honor that oath, and sometimes it comes at a huge sacrifice."

Cassandra Cookson said she is still healing, both mentally and physically, and said it’s not the same without her husband.

"Sean, he was amazing. He was a big sweetie. Like, he was 6’-8’’ and size 16 shoes, but he was just a teddy bear," she said.

With prayers and memories shared, law enforcement officers stood with Cassandra and others who knew the officers who sacrificed their lives.

Cassandra said the support is overwhelming.

"It touches my heart deeply because, like right now we got to stick together, especially, like, with all the losses we've had. I know they have my back because I saw these guys in the hospital when me and my husband were struggling," she said.
