A former FBI special agent says the fatal stabbing and home invasion of a country singer’s mother may not have been “random.”

Virginia authorities said a man killed 62-year-old Holly Hatcher, a former teacher, around midnight on Aug. 3 at home in Rockingham County during a home invasion. Michael Hatcher, 65, shot and killed the intruder, who was identified by officials as 41-year-old Kevin Moses Walker.

The couple’s son, 31-year-old Spencer Hatcher, is an up-and-coming country singer who announced he is canceling several of his upcoming shows following his mother’s death.

Rockingham County Sheriff Bryan Hutcheson said Walker had no known criminal history and is from Pikesville, Maryland, which is about a three-hour drive from the Hatcher’s residence. The sheriff said that the home invasion was random and “highly unusual,” adding that Walker had brought a “large knife” into the home.

Former FBI special agent Jonathan Gilliam told Fox News Digital he questions whether the home invasion and subsequent stabbing was random.

The Endless Caverns are just 3.5 miles from the Hatcher family home, where authorities say 41-year-old Maryland man Kevin Moses Walker broke in with a knife and attacked the parents of country singer Spencer Hatcher. Walker killed 62-year-old Holly Hatcher with a knife before her husband, who was also injured, shot him dead. (Google Earth)

Saturday, Aug. 2

• 6:37 a.m.: The Virginia State Police received a call regarding a vehicle that was abandoned and believed to have been involved in some kind of crash in the area of the campsite.
• Hutcheson said the vehicle belonged to Walker, adding that the car was properly registered and not stolen. Inside the car, the sheriff said there was a one-night Endless Caverns parking pass. State police went back to Endless caverns to try and find Walker but found that the campsite store had been broken into and “rammed by a motor vehicle.” Hutcheson said the damage was consistent with damage found on Walker’s abandoned car.
• According to Hutcheson, nothing was stolen from the store. Checks run by police on Walker found that he wasn’t wanted for any crime. Virginia State Police attempted to locate Walker, but he wasn’t found. Felony warrants were obtained for Walker.
• Mike Stewart, the general manager at Endless Caverns, said that Walker came across as polite, stating: “He was a ‘yes ma’am, no sir,’ person, just didn’t register any aggressiveness on our part … that’s why everybody’s looking for answers.”

Spencer Hatcher said in an Instagram post that his planned performances at the VOA Country Music Fest in Ohio and the Rockingham County Fair in Harrisonburg, Virginia, have been canceled.
