ACSO: Man charged with murder in fatal Heiskell shooting after leading authorities on manhunt to VA and through East TN

The Anderson County Sheriff's Office identified the suspect as Jason Dockery on Wednesday.

ANDERSON COUNTY, Tenn. — UPDATE (9/15): A captured fugitive is now charged with murder in the deadly shooting of a 38-year-old woman in Heiskell.

According to court records on Friday, Jason Dockery is charged with felony first-degree murder. He was wanted in the shooting of 38-year-old Shysti Renea Mayberry. 

Dockery, Mayberry and her 21-month-old daughter were all in the car when he pulled out a pistol and shot Mayberry, an arrest warrant reported.

After she was shot, Mayberry attempted to get out of the car, but Dockery continued to fire at her six times until she fell on the side of the road. The warrant said that Dockery fled the scene with Mayberry's daughter still in the car.

Union County Sheriff's Office deputies arrested Dockery on Thursday after someone spotted him walking on Maynardville Highway. According to UCSO, deputies took him into custody outside the Milan Missionary Baptist Church.

According to ACSO, authorities took Dockery into custody around 2:45 p.m.

Dockery was also wanted for violation of probation in Sevier County, as well as felony evading, reckless endangerment, child abuse, neglect and endangerment and multiple traffic violations in Claiborne County. 

"We work best when we work together, and here the collaboration, dedication, and tireless efforts have played a crucial role in bringing the suspect into custody," Anderson County Sheriff Russell Barker said.

ACSO said it would provide additional details into the investigation as those become available. 

The Claiborne County Sheriff's Office also released a statement about the arrest. In it, they said Dockery may have had a cell phone and was monitoring social media to try and evade capture. CCSO also said deputies spoke with someone who have him a ride to Union County, which was confirmed by video footage.

Dockery's bond is set at $2 million. He is due back in Anderson County court on Sept. 27.

ORIGINAL STORY: 

Law enforcement officials are searching for a man who allegedly shot and killed a woman while on the side of the road Tuesday, the Anderson County Sheriff's Office said.

Officials identified the shooting victim as 38-year-old Shysti Renea Mayberry. She was shot around 1 p.m. in the 200 block of Moores Gap Road in Heiskell, ACSO said. 

The East Tennessee Valley Crime Stoppers announced Thursday morning that Jason Dockery is believed to be in the Knoxville or Clinton area. 

If you see Dockery, do not approach him. He is considered armed and dangerous. 

If you have information on Dockery's whereabouts, you can contact ETVCS at 865-215-7165. 

The suspect, 44-year-old Jason Dockery, who has a long arrest history dating to his teens, is believed to have at some point stopped Tuesday at a home in Union County. He "left an infant child" and made his way to Claiborne County, according to ACSO. 

Authorities then pursued him in Claiborne County, but the chase ended around 3 p.m. in Lee County, Virginia, when he ran into the woods. The vehicle he was driving was recovered and returned to Anderson County for evidence processing.

As of Wednesday, multiple law enforcement officials were still attempting to locate Dockery. Lee County Public Schools are closed because of the search. 

However, by 6:30 p.m., Lee County Sheriff Gary Parsons said authorities confirmed Dockery was no longer in the area. His full statement is below.

"We have confirmed that the Suspect in the Manhunt has left Lee County, Virginia but because of the sensitivity of the ongoing investigation, no further information can be released at this time. Once resolution of the investigation is completed Sheriff Parsons will provide another official update."

The U.S. Marshals said they started looking further south to investigate leads and said Dockery could be reaching out to contacts for help. They also confirmed that Dockery found a ride to the Union County area and have stopped searching for him in the Lee County area.

"We will fully prosecute anyone who knowingly provides assistance to him," they said.

They said Dockery is about 5'6" tall, believed to be armed and is "a very dangerous individual." They are offering a $5,000 reward for information leading to his arrest.

Dockery just pleaded guilty in June to aggravated assault in Sevier County after facing multiple charges that included aggravated kidnapping of a woman. In that case, he is serving a four-year sentence on supervised probation, according to court records.

A Sevier County grand jury indicted him in the case in 2021. Records allege he choked the woman in May 2020 and fired a gun in her home. She is not the same victim who was shot and killed Tuesday in Anderson County.

Dockery's Sevier County violation of probation documents aren't public yet because he hasn't been served with them, court officials said.

Dockery, who has lived in Knoxville, has a conviction record that includes aggravated assault (failure to protect a child); multiple counts of theft for various incidents; aggravated burglary; multiple counts of evading arrest through the years; driving without a valid license; public intoxication; marijuana possession; disorderly conduct, records show.

If you have any sightings, tips or information about Dockery's whereabouts, call 911, email USMS84.TIPS@usdoj.gov, or call the Lee County Sheriff's Office at 276-346-7777.

Anyone with information about his location can also reach out to the Anderson County Sheriff's Office at (865) 457-2414, Ext. 9, to be directed to U.S. Marshals.
