The family of a Cobb County man is pleading for help finding the gunman who shot him to death in his driveway, Saturday night.

53-year-old Milton Kelley was shot four times outside of his house on Leicester Drive after returning from the store.

His daughter, Shawna Welch, tells Channel 2 Action News she doesn't know who would want to hurt her father.

"This is probably the worst pain I've ever experienced," said Welch. "We were very close. Very dear to my heart. He's our dad."

Kelley's other daughter, Tesha Arnold, says he was a great father, a helpful neighbor, and a health nut.

"Just to be so healthy and then to be taken out by somebody," said Arnold. "For such a senseless act to happen when he has helped so many people."

Police say they're following up on several leads.
