CHATTANOOGA (WRCB) - Family and friends gathered to pay their last respects to Jason Hood.

The Army and Air Force vet was killed last Wednesday, allegedly by his cousin, 59-year-old William Clarke, who said it was self defense.

Hood's family tends to think it's a different story.

"We know that Jason would have never initiated any kind of attack, certainly not on his own kin. We also know he is not here to tell his side of the story," Hood's aunt, Joy Casteel said.

That's why the family said its their duty to do so.

Hood served in Bosnia, Korea, and Iraq before being honorably discharged in 2007.

His uncle, Larry Casteel, said Hood was like a son to his family and his loss is greatly felt. "He was a fun loving kid that would not hurt a fly and we just hurt for him right now."

Family members said Hood was between jobs at the time of the shooting and had been doing work for Clarke to get back on his feet.

It's still unclear what sparked the argument between Hood and Clarke, but Larry Casteel said Hood was far from a violent person.

Now the family says they hope the truth is made public, so Hood's death, won't be in vain.

Joy Casteel said, "It is what it is pure and simple, a senseless murder."

"We want to see justice done, he was murdered. We want to see the guilty party brought to justice," Larry Casteel said.

Police have charged Clarke with murder and an autopsy will reveal more about how Hood died.

That's not available as of yet.

Clarke is due in court April 22nd.
