The Owasso Police Department is investigating after two people were found dead in a home near East 80th Street North and North 129th East Avenue.
Police say a relative went to the house to check on a husband and wife who lived there. When no one responded, the relative called 911.
Owasso police responded to a welfare check at the residence after the family member said they were unable to contact the couple.
Officers went inside and found 36-year-old Matthew John Clark and 29-year-old Eva M. Clark, both apparently killed as a result of gunshot wounds.
Police are now trying to determine what led the shooting.
Detectives are still investigating, however, initial evidence suggests this incident was a murder/suicide, police say.
