Police probe Kentucky shooting that left 4 dead

CADIZ, Ky. - Kentucky State Police detectives were trying to figure out Monday what led to the shooting deaths Sunday of a married couple, their adult daughter and another man in an apparent murder-suicide in western Kentucky over the weekend.

State police say the man, 22-year-old Vito Y. Riservato, is suspected of shooting the others at their home in Cadiz. Lindsey Champion, 62; his wife, 60-year-old Joy A. Champion; and the couple's 31-year-old daughter, Emily K. Champion, were found dead along with Riservato.

State Police Trooper Jay Thomas said police are looking into the relationship between the Champion family and Riservato, who lived about 20 miles away in Hopkinsville. Thomas says Riservato may have known the family briefly prior to the shooting.

Emily Champion was a veterinarian at Baronne Veterinary Clinic in Sunset, Louisiana. She graduated from Auburn University's college of veterinary medicine in 2008 and had worked at the clinic since 2009, according to her biography on the clinic's website. Joy Champion is a retired teacher who taught for 30 years at schools in Trigg County.

The Champions' home in Cadiz is located about 40 miles northwest of Clarksville, Tennessee.

Thomas said detectives wrapped up investigating at the crime scene early Monday morning, but they still have some vehicles to search and family members and acquaintances to interview.

"We're still trying to fit some pieces into the puzzle about the whole situation," Thomas said.

Autopsies will be performed Tuesday in Madisonville, Thomas said.
