DALLAS -- Sgt. Michael Smith leaves behind a legacy of love.

His wife, Heidi, and daughters, Victoria and Caroline, are trying to find answers about why he died so violently.

"Caroline asked me, 'Why did God do this?'" Reverend Michael Forge said during Smith's memorial service Wednesday. "I immediately answered, 'God didn't do this. The anti-God did this. Evil did this."

Smith was one of five police officers killed last Thursday in an ambush by a gunman with a rifle in downtown Dallas.

Rev. Forge talked about one of Sgt. Smith's final and touching moments.

"Heidi shared before Mike left for the evening he told Caroline to kiss him goodbye like it was his last time," he said. "I looked at Caroline and said, 'God did that. That’s what God did.'"

Sgt. Smith was devoted to his family, faith, and fellow man. At work, he was one of the best.

"I was told several times that even those he arrested were treated with respect, dignity, humanity," said Smith's sister, Yea-Mei Sauer.

His former partner, Detective Marcie St. John, recalled the moment she heard Michael was among the fallen. She got a call from a DPD officer while watching the tragedy unfold on television.

"She was at the hospital and she told me, and I pretty much screamed, fell on the floor, cried in my pillow," St. John said.

His sister says she is full of rage about her big brother's senseless and unjust death, and wondered what he would say in these difficult moments.

"He would tell me to pray. Use that brain in that head of yours and listen to your heart," she said. "My brother's murder will not be in vain, and his selfless legacy will live on, and he would want us to continue the fight."

His family and friends say they know Mike will now be watching over them as they continue to protect and serve.
