ST. CHARLES, Mo. (AP) -- A Missouri judge on Friday rejected a murder suspect's bid to question an investigator who signed a complaint that could send him back to Illinois to face charges in the deaths of his wife and three children.
Christopher Vaughn's attorney sought to depose Illinois State Police Sgt. Gary Lawson as part of an effort to block extradition.
Defense attorney David Waltrip argued that the complaint Lawson signed fails to meet Missouri's legal requirements to link Vaughn to the killings.
Prosecutors argued that Missouri law only allows defendants to challenge whether extradition papers are in order, not dig into the underlying charges.
Vaughn is jailed without bond pending a July 25 hearing on whether he should be returned to Will County, Illinois, to face murder charges in the June 14 deaths of his wife and children.
