Man Wanted in Connection with Brother's Murder; Ex-girlfriend Missing

WINCHESTER, Va. - Investigators spent Friday searching the banks of the Shenandoah River for a 22-year-old woman whose disappearance coincided with a manhunt for her ex-boyfriend, a suspect in the murder of his brother.

The mother of Kayleigh Marie Plamondon publicly pleaded for help finding her daughter Friday.

"We miss Kayleigh. We love Kayleigh. We want Kayleigh to be found," said Debbie Plamondon, pleading for 21-year-old Justin Shane Slater, who is wanted on a murder warrant, to contact her. "I really need to hear from you now, because if I can go to Kayleigh, that will be my next step," she said. "My next step is to find her and make sure that she's safe and that I can help her."

Kayleigh Plamondon was last seen Wednesday afternoon. Investigators searching the farm where she was house sitting came across disturbing signs.

"There was significant evidence to believe that there was a violent confrontation at the house that she was sitting at," said Investigator Trisha Putnam with the Clarke County Sheriff's Office.

Justin Shane Slater, 21, should be considered armed and dangerous, according to the Frederick County, Va., Sheriff's Office.

The body of Slater's brother, Gregory Scott Slater Jr., 28, was found early Thursday morning. He had been shot to death, police said. Justin is wanted on a first-degree murder warrant in connection with the shooting.

Slater is described as 6'1", 170 pounds, with brown hair and green eyes. He is believed to be driving a 1999 Jeep SUV, brownish gold in color, with Virginia tags XXG3569, investigators said. The vehicle has flaring on the wheel wells and window tinting on the right side, but not the left side, police said. The back, driver's-side compartment window is also broken, according to police.

Investigators ask anyone who sees Slater or the vehicle to call 911 immediately.
