CAMDENTON, Mo. — A Missouri man has been charged with two counts of first-degree murder in the deaths of a mother and daughter whose bodies were found after a fire destroyed their trailer.

The Camden County Sheriff said 54-year-old Steven Ray Endsley was arrested early Saturday. He is charged with first-degree murder, armed criminal action, burglary and arson in the Aug. 29 deaths of his neighbors, 27-year-old Danielle Smith and her mother, 61-year-old Teresa Jackson.

The sheriff said in a news release that Endsley had an ongoing disagreement with Smith over her sexual orientation. The FBI is helping to investigate whether the killings would be considered a hate crime.

Two other members of Endsley’s family were taken into custody for questioning but had not been charged Saturday.
