A damaged street sign along with food allegedly stolen from a Buffalo Wild Wings in Virginia, helped authorities uncover a murder plot against the parents of one of two suspects arrested last week, officials said.

The investigation began on June 16 when authorities responded to a report of reckless driving in Stafford after a vehicle veered off the road and struck a road sign, according to the Stafford County Sheriff’s Office.

Deputies located the vehicle at a Wawa convenience store and detained two suspects: Louis Conely and an unidentified 17-year-old.

Both were found with unopened alcoholic beverages and a tray of food stolen from a Buffalo Wild Wings visible on the vehicle’s dashboard, authorities said.

The pair allegedly admitted to stealing the food tray from the restaurant.

As deputies searched the vehicle, they found opened alcoholic beverages, multiple knives, medical items and a notebook detailing a murder plot.

Conely, 19, owned the notebook, authorities said.

Investigators revealed that the evidence showed the pair had developed two detailed murder plots against the underage suspect’s family.

In April, they allegedly sent text messages planning the murders of the 17-year-old’s parents inside their home, discussing how to avoid security cameras and debating whether to shoot the parents or slit their throats, Fox 5 DC reported.

A search of the underage teen’s bedroom uncovered multiple BB guns, edged weapons and archery equipment, according to charging documents obtained by the news outlet.

Authorities have not yet disclosed a motive.

Conely faces a slew of charges, including two counts of conspiracy to commit murder, two counts of felony written threats, petit larceny, unlawful purchase of an alcoholic beverage, drinking while operating a motor vehicle, contributing to the delinquency of a minor, possession of a Schedule IV controlled substance, hit-and-run and reckless driving.

Conely was held at the Rappahannock Regional Jail without bond.
