On March 13, 2020, Nashville Metro police received a 911 call made by a construction worker who saw a white Acura that hit a tree.
Inside the vehicle were the bodies of Holly Williams and Bill Lanway, an esthetician and a mechanic respectively, who were shot several times, according to investigators.
The three-year investigation into their murders would uncover a whole host of secrets, including an illicit affair and a conspiracy.
“This was like a scene out of a movie,” Metro Nashville PD Det. Patrick Cuthbertson, one of the case’s investigators, said.
“20/20” will explore the case in an episode airing Friday, Feb. 9, at 9 p.m. ET and streaming on Hulu the next day, featuring exclusive interviews with the people who investigated the murders and brought those responsible to justice.
Friends of Williams told “20/20” that they thought the relationship between the couple was toxic. Williams installed security cameras in her apartment because of reported domestic disputes with Lanway.
Investigators sought out the security footage from around the time the couple’s bodies were found.
Det. David Willover, of the Metro Nashville PD who investigated the case, told “20/20” that his team caught a break when they saw footage of men approaching Williams’ apartment door earlier in March 2020, before the murders.
“They’re doing things to hide their identity,” he said.
Indoor cameras showed Williams pacing through her home and bolstering the door in the event the men outside tried to get in.
Investigators looked more into Williams’ background and found out she moonlighted as an escort with the name “Layla Love.”
With no leads from the footage of the mysterious men seen on the surveillance video, investigators next turned to the couple’s phone records. They noticed one number that was found in both of their records, which was a Voice Over IP (VOIP) telephone phone number.
Those numbers are sometimes used to hide the caller’s identity but they leave a trail of computer code IP addresses that can be examined, Willover said.
Investigators eventually matched that particular phone number to Adam Carey, a former Marine with special ops training and a criminal record who was living in North Carolina and working in private security.
Carey’s driver’s license photo matched the face of one of the men captured on Williams’ cameras, according to Willover.
