Nearly twenty-two months after Timothy “Asti” Davison was shot and killed on Interstate 81 outside of Greencastle, a murder suspect has been charged.

John Wayne Strawser, 38, of Terra Alta, West Virginia, was charged with first-degree murder today, according to a release from Franklin County District Attorney Matt Fogal. According to Fogal, the initial attack on Davison by Strawser may have been specifically intended for someone else.

Strawser is already jailed in West Virginia for allegedly killing his girlfriend, Amy Lou Buckingham, in April.

*** Initial incident recap ***

Davison, 28, was shot and killed on Jan. 4, 2014. Davison was returning home to Portland, Maine, from Florida when he called 911 around 2 a.m. to report he was being chased by another motorist who was shooting at him on northbound I-81 in Maryland.

Shortly after crossing into Pennsylvania, Davison’s Mitsubishi Montero was rammed into the median near Exit 3 before Strawser reportedly got out and fired into Davison’s vehicle, killing him, according to Pennsylvania State Police.

*** Intended victims ***

On April 20, 2015, state police were contacted by Jamie Breese, who told them about John Wayne Stawser and that Davison’s attack may have been intended for he and his wife, Courtney. He explained that he and his wife knew Strawser and had contact with him on the night of Jan. 3, 2014, into the early morning of Jan. 4, according to Fogal’s release.

The release added that Breese told investigators he thought that Strawser had mistaken Davison's Montero with their silver Honda Pilot. When he had heard that Strawser was recently charged with similar crime in Preston County, West Virginia, he believed his information could be relevant to the Pennsylvania State Police.

Further, he explained that Strawser's truck was a dark Ford Ranger. It is currently black and green in color, but it had been painted sometime after Jan. 4. Additionally, he indicated it had previously had left front damage.

Breese and his wife further recounted their history with Strawser, and how he had repeatedly contacted them on the night of Davison's murder. According to the release, as they received more messages and threats from Strawser, they left Cloud Nine strip club in Bunker Hill, West Virginia, and traveled north on I-81, in the same direction Davison would have been going.

Initial evidence recovered at murder scene

— PennDOT video from Jan. 4, 2014, showed a vehicle approach and ram Davison's vehicle into the median on I-81, and then travel south on I-81.

— In his 911 call, Davison described a dark Ford Ranger as the one his shooter was driving, and that it had made contact with his vehicle.

— A spent .44 casing was found at the murder scene. A DNA profile was later developed from the casing.

— A Ford Ranger XLT emblem was found at the murder scene on the I-81 median, which would have been on a 1996-2006 Ford Ranger.

— The paint transfer on Davison's vehicle was a "lapis" color used on models of Ford Rangers between 1993-1997.

— The Garmin GPS inside Davison's Montero showed steady speeds from Florida, but a marked increase starting in Martinsburg, West Virginia.

Linking evidence to Strawser

The evidence gathered in the next phase of the investigation, focused on John Wayne Strawser, yielded the following results, according Fogal:

— PSP confirmed that Strawser owned 1997 Ford Ranger with dark lapis paint.

— Cell tower information regarding his mobile phone shows that Strawser was on a call between the area of Martinsburg and Hagerstown. Records also show that the call was terminated while his phone was in Hagerstown, and just three minutes before the first 911 call was received from Timothy Davison. The cell tower records likewise confirm he made repeated harassing calls to Courtney Breese that evening.

— Strawser's truck, when seized, had some original dark blue color, though it had been painted. It was also outfitted with what appeared to be new parts.

Fogal’s statement also said that a friend of Strawser's led police to a field Strawser frequented, where they found a gun, a Rossi Ranch Hand hidden in a box. Police discovered and seized live .44 rounds and spent casings within Strawser’s residence which lab testing matched the casing found at the murder scene fired from the Rossi Ranch Hand.

According to court documents, a DNA profile was obtained from Strawser, which matched the profile previously created from the casing found at the murder scene. In addition, the investigation revealed that Strawser's Facebook page showed pictures of the Rossi Ranch Hand, as well as pictures of his Ford Ranger with blue paint as well as the newer black/green paint.

Inside the driver’s side of Strawser’s Ford Ranger were particles characteristic of gunshot residue, according to Fogal’s release.

“I thoroughly applaud the long suffering and tireless efforts of the Pennsylvania State Police during the course of this investigation, and to Troopers Jason Cachara and David Rush in particular,” Fogal said.

Davison’s family who reported their Facebook page Sunday night that an arrest was to be announced today, had encouraged tips and offered rewards for information leading to the arrest for the last 21-plus months.

“Law enforcement mourns with them (Davison’s family) and stands by their sides. We sincerely thank them for their patience,” Fogal said.

Strawser’s preliminary hearing has not been scheduled.
