OWASSO, Okla. - Owasso police are investigating the city's first homicide of the year.
Police say 38-year-old Edward Templeton was shot and killed outside of a home around 5 p.m. Sunday.
Investigators say it's not clear if the shooting was a justifiable homicide or a murder, a decision that will be up to the Tulsa County district attorney.
"They discovered a homeowner had shot and killed a person who was trying to make forcible entry into their home," said Deputy Chief Scott Chambless with the Owasso Police Department.
Officers confirm Templeton, his wife and son and the homeowner were friends and were all together inside the home earlier in the day.
"It's our understanding that prior to our arrival that the homeowner and the deceased were involved in verbal argument and a physical altercation," Chambless said.
Under Oklahoma law a homeowner has the right to protect themselves inside their own home.
If Templeton had a right to be there, however, murder charges could be filed against the homeowner.
"Anytime circumstances like this arise and there's a relationship involved and people know each other, there's going to [be] other questions in the investigation," Chambless said.
If there are charges, it would mean the first murder for Owasso in nearly a decade.
"We haven't had a murder in Owasso in almost eight years, we have had incidents again with justifiable defense and those types of circumstances," said Chambless.
Investigators say there is no indication that the homeowner was intoxicated, but it will be up to the medical examiner to determine if the victim was.
A decision about the possible charges is expected by the end of the week.
