A Harrison County man charged with killing his seven-year-old son appeared in a Buchanan County courtroom Tuesday.

Investigators say Tony King, 28, strangled Jeremiah Lamm in January and then set fire to a mobile home near Bethany with the boy’s body inside.

King is scheduled for trial here next March.

He is charged first degree murder, second degree arson and felony child abuse.

Circuit Judge Randall Jackson heard pre-trial motions in the case on Tuesday. Harrison County Prosecutor Johnathan Meyer asked the court for an order to preserve testimony. Meyer will interview Harrison County Sheriff George Martz on July 9.

The court also okayed a new defense lawyer for King, who is being held in the Buchanan County Jail. The case was transferred to Buchanan County earlier this year.
