Unattended Death Cleanup OKAn unattended death is defined as a death that occurs when another person is not with the deceased. The death can be the result of a health event, natural causes or an accident, but it is particularly difficult because by the time a friend, neighbor or family member finds the person, decomposition has often started, making the area unsafe for others. Oklahoma unattended death scene cleanup is an essential part of the process of restoring the area to safety and helping friends and family come to terms with the death and move forward.
