ARDMORE, OK- Elzie Cain's family and friends traveled to Arkansas for the trial and were in the courtroom when the verdict was read Wednesday.
Elzie's father Dalton said, "No matter the outcome of the trial it was not going to bring him back. That is just the way we have got to look at it. I've said it the whole time from the first day, that there is not much we can do, there is not many ways we can help the dead."
25-year-old Aaron Threlkeld was cleared of any wrong doing during the Sept. 2010 altercation with Elzie which ended in his death.
Which Elzie's father and prosecutors said it started over jealousy of a woman.
Police said Elzie was punched and suffered a skull fracture when his head hit the floor, he was taken to the hospital where he later died from brain injuries.
"It's not the first time jealousy has killed somebody," Dalton said.
Dalton said he was not surprised to hear the not guilty verdict but thinks things might have been different if Elzie was there to tell the his side of the story.
Ardmore Police Captain Eric Hamblin said, "Elzie was a wonderful person, a wonderful father, a wonderful police officer and we miss him and again we are disappointed in the verdict."
"He's got a one year old little boy that has the same smile from ear to ear but he wont get to go fishing, with his dad anyway," Dalton said.
And that smile is what his dad said drew so many people to Elzie.
"They will miss out on a lot, everybody that knew him," Dalton said. "Even the girl that was there that night says she fell in love with him the minute she saw him. I can't speak for the rest of the family but you don't see the happy things, when you go to bed or when you get up you look at him laying in the hospital bed."
Elzie was on a forty-five day leave from the Ardmore Police Department at the time attending National Guard sniper training in Arkansas.
He planned to deploy for Afghanistan earlier this year.
