A man accused of killing his wife and three children near Chicago has decided to fight extradition to Illinois and will remain in Missouri until at least the end of July.

Attorney David Waltrip represents Christopher Vaughn in the extradition proceedings filed to move Vaughn from the St. Charles County jail to the Will County, Illinois jail. Waltrip is using all the time provided him by law to review the extradition order and prepare a case against it. The governors of Missouri and Illinois worked quickly to expedite the move across the state line, but the legal process has kept that from happening. An extradition hearing will be held July 25 th . Vaughn will remain in the St. Charles County jail until the hearing. He is being held without bond.

Vaughn, 32, faces eight counts of first-degree murder in Illinois. He is accused of killing his wife, 34-year-old Kimberly Vaughn, and their three children, Abigayle, 12; Cassandra, 11; and Blake, 8. They were found dead June 14 inside the family’s SUV near Chicago. Christopher Vaughn had been shot in the leg.

The family is originally from St. Charles. Authorities arrested Vaughn before a memorial services for his family in St. Charles.
