HENRYETTA, Oklahoma - Oklahoma State Bureau of Investigation agents are looking for Christopher Hathcoat after they say he opened fire inside a home in rural McIntosh County Friday.

The home is a rural area near Henryetta.

Special Agent Ben Rosser says it appears a fight or struggle happened before Hathcoat shot and killed his dad Floyd and the other man who hasn't been identified.

Rosser says the family hopes Christopher is caught.

"Everybody wants closure and justice, so until he's brought in he's still a potential threat to the public and they (family members) don't want anyone else hurt,” said Rosser. “They want him to be accountable for what he's already done, allegedly done."

Prison records show Hathcoat served time for robbery and kidnapping.

"[It’s] real important [that we catch him]. I mean if he's already killed two people what's to say he couldn't harm of kill someone else,” said Rosser. “He's got nothing to lose at this point."
