MARYLAND HEIGHTS, Mo. (AP) — A woman pleaded guilty Monday to several charges in the stabbing deaths of a suburban St. Louis man and his toddler son in 2018.
Onyai S. Turner, 25, of St. Louis, entered the pleas for her role in the deaths of Malcom Mathis II, 33, and his 22-month-old son, Malcom Mathis III, the St. Louis County prosecutor’s office said.
Turner’s boyfriend, Traveon Sims, was sentenced to life in prison without parole last year after pleading guilty to two counts of first-degree murder in the deaths.
Prosecutors say Turner and Sims carried out the attack at Mathis’ home in Maryland Heights in February 2018. Sims was Mathis’ nephew.
Sims’ grandmother and Mathis’ 4-year-old daughter also were stabbed several times but survived.
Turner pleaded guilty to second-degree murder, second-degree felony murder, first-degree robbery and three counts of armed criminal action.
Authorities said Mathis had kicked Sims out of their home months before the attacks.
Turner was scheduled to be sentenced April 29.
