Kelsey Shelton Smith-Briggs was born December 28, 2002, in Oklahoma City, Oklahoma, to divorced parents. She lived with her mother and maintained contact with her paternal family. The first two years of her life were uneventful, and no signs of abuse were reported to authorities or noticed by family members or day care staff before January 2005.
Beginning in January 2005, Kelsey suffered several documented and confirmed incidents of child abuse, including a broken collarbone, broken legs, and multiple bruises and abrasions on her face and body. On January 17, 2005, the Oklahoma Department of Human Services (OKDHS) first confirmed abuse against Kelsey's mother after Kelsey was taken to a local emergency room with a broken collarbone and multiple bruises and abrasions to her lower back, buttocks, and thighs. In April 2005, both of Kelsey's legs were broken; medical examiners determined these were spiral fractures in different stages of healing caused by child abuse. Following this, Kelsey was placed into OKDHS custody.
On June 15, 2005, Associate District Judge Craig Key placed Kelsey into the home of her biological mother, Raye Dawn Smith, and stepfather, Michael Lee Porter — against an OKDHS recommendation — stating that the abuser was "unknown."
Kelsey died on October 11, 2005, at the home of her mother and stepfather in Meeker, Oklahoma. Her death was ruled a homicide caused by blunt force trauma to the abdomen. Kelsey had been "closely" observed by OKDHS from January 2005 up to and including the day of her death.
Michael Lee Porter, Kelsey's stepfather, was charged with sexual assault and first-degree murder. In February 2007, he pleaded guilty to enabling child abuse and was sentenced to 30 years in prison. Raye Dawn Smith, Kelsey's biological mother, was convicted on July 18, 2007, of enabling child abuse and was sentenced to 27 years in prison; her request for appeal was denied.
In March 2006, the Oklahoma state legislature passed the Kelsey Smith-Briggs Child Protection Reform Act to reform how courts and OKDHS handle child abuse and neglect cases. The bill's co-author, Senator Harry Coates, presented the measure in committee.
