VERNAL, UT. (THECOUNT) — Mckenley Yadon has been identified as the Utah stepmother arrested on aggravated murder and child abuse charges after her 3-year-old stepdaughter died by asphyxia due to smothering, court documents state.
Yadon, 24, twice admitted to attempting smothering of the 3-year-old to death and gave a detailed account of the incident, this after police responded to a report of a child choking at a residence on March 14 at approximately 11:46 a.m.
Upon arrival, police found the child unresponsive, not breathing and cold to the touch, court documents state.
After the child stopped breathing and moving, Yadon said she waited 10 to 15 minutes before contacting a friend, to whom she recalled an inaccurate account of events, court documents state.
