Kenneth Lanman was a 3-year-old boy murdered on September 27, 1989, in his home near Belleville, Illinois. Kenneth and his mother, Jolaine Lanman, were found dead by his father, John Lanman, that evening. Both victims had blunt trauma to the head and stab wounds to the neck; a pair of scissors was found protruding from Jolaine’s neck.

Investigators arrested Dale Anderson; he was convicted of the murders in 1990 and sentenced to life in prison. Prosecutors said Anderson had been fired from the Illinois Department of Public Aid about a year earlier and argued he killed Kenneth and Jolaine to frame his former supervisors. A note left under Jolaine’s bed listed license plate numbers of agency vehicles and was presented at trial; the prosecution’s case relied on that note and other circumstantial evidence and witness testimony. Anderson maintained his innocence.

Does anyone have memories of the Belleville area in 1989 or information about the victims or the note left at the scene?
