Richardson Police tweeted a touching last radio call for Officer Sherrard Tuesday afternoon.

“I’m going to miss David. I’m so blessed that we made it to our 15 year anniversary in November and that we made the most out of celebrating it,” said his widow, Nicole, during the service. “I’m going to miss our love, our laughs. Our silly times and banter. Our double date nights. Cuddling, cuz Dave loved to cuddle.”

On Facebook Live Tuesday night, CBS11 played some of Nicole Sherrard’s eulogy on some of the very difficult moments of their marriage and how they overcame them until they “finally had the perfect marriage.”

Police Chief Jimmy Spivey called Sherrard a “true hero.”

Authorities say the 37-year-old officer died Feb. 7 at a hospital hours after he was shot while entering an apartment. Police say another man was found shot dead at the scene.

The suspect, Brandon McCall, eventually surrendered and remains jailed without bond on capital murder charge. Investigators are trying to determine what prompted the disturbance.
