Grayden Denham
The Edgerton man accused of murdering his grandparents, his sister and infant nephew in 2016 has been committed to the Missouri Department of Mental Health.
Grayden Denham, 28, remains in custody at the Platte County Detention Center, but his jury trial scheduled for November has been cancelled. A status review is set for September in the case.
Platte County prosecutor Eric Zahnd had previously announced his intent to seek the death penalty in the case.
The charges against Denham, which were filed after a grand jury indictment, include four counts of first degree murder and four counts of armed criminal action in the Feb. 19, 2016 homicides of his sister Heather Ager, 32, his three-month-old nephew Mason Schiavoni, his grandmother, Shirley Denham, 81, and his grandfather, Russell Denham, 82.
Denham is also charged with felony arson for destruction of the family home, a felony for tampering with evidence, a felony for stealing his grandparent’s vehicle and a misdemeanor for animal abuse.
According to online court records, a motion to find Denham incompetent to proceed with trial was filed on Tuesday, March 17 and was approved by judge James Van Amburg on March 18.
