New charges were filed against three people Tuesday and Wednesday in a case surrounding the alleged stalking of two Norfolk Southern coworkers.

In March, police charged Hollidaysburg resident Donald Byers, 46, with the alleged stalking of Indiana resident Bailey Brendlinger, 22, and a coworker, with whom she had a relationship.

New charges, however, allege Brendlinger was aware of Byers’ efforts to stalk the victim in an effort to hide her intimate relationship with Byers from the victim, court documents stated.

During the initial investigation, police discovered Byers paid for a GPS tracking device the victim found under his vehicle and turned over to the police.

While reviewing thousands of screenshots of Byers’ messages to both Brendlinger and the victim, police discovered some messages alluded to a relationship between Byers and Brendlinger, including messages in which she acknowledged the tracking device and offered to pay for a portion of it, police reported.

In other messages between Byers and Brendlinger, Brendlinger mentions a sexual relationship between the two, adding the victim would “kill us both” if he found out, court documents stated.

While executing a search warrant on digital devices found in Byers’ house, law enforcement located several photos sent to Byers by Brendlinger, some of which were partially and fully nude, police reported.

Although Byers was terminated from Norfolk Southern — where he worked with Brendlinger and the victim — after the company investigated a complaint in 2019 that Byers was harassing the victim through text messages, police discovered Byers received password information to access the Norfolk Southern mainframe database in 2021.

The information was given to Byers on multiple occasions by Cherry Tree resident James Pedersen, 62, who was working for Norfolk Southern at the time of the requests, police reported.

Pedersen was arraigned Tuesday by Magisterial District Judge Paula Aigner on three felony counts of unlawfully providing password information. He was released on an unsecured $25,000 bond.

According to court documents, Pedersen did not ask what Byers was using the information for.

Photos on Byers’ phone showed Byers was using the mainframe data to record which employees were operating certain trains at what times, police reported.

Summons were issued to Brendlinger for multiple misdemeanor charges including stalking and harassment. Her preliminary arraignment and hearing are scheduled with Aigner for July 13, court documents state.

In addition to Byers’ prior stalking charges, he was arraigned by Aigner on Friday regarding nine felony counts of computer-related crimes. Court documents stated Byers’ waived the preliminary hearing on his most recent charges, so his case will continue to the Blair County Court of Common Pleas.
