Border Patrol Agent Killing Linked To Unsolved Delco Double Murder

CHESTER HEIGHTS, PA — Pennsylvania State Police said a woman accused of killing a United States Customs and Border Patrol Agent recently is connected to an unsolved double murder in Delaware County.

On Jan. 20, 21-year-old Teresa Youngblut, along with a German companion, shot and killed Border Patrol Agent David Maland in Coventry, Vermont, federal authorities said. The German man was also fatally shot.

State Police Wednesday said an investigation into the Jan. 20 shooting revealed that the weapon used in Maland's killing was purchased by a person of interest in the murders of Rita and Richard Zajko, ages 69 and 72, respectively.

The Zajkos were found dead in their home at 18 Highland Drive in Chester Heights Borough on Monday, Jan. 2, 2023. Authorities said they were shot to death on Dec. 31, 2022.

"The Criminal Investigation Unit has executed numerous search warrants, conducted dozens of interviews, and have obtained new evidence regarding this homicide," state police said in February 2023. "Based off this information it is believed at this time not to be a random act of violence."

Anyone with information about the Zajko's deaths is asked to call the Pennsylvania State Police, Troop K, Media at 484-840-1000 or anonymously contact the Pennsylvania Crime Stoppers Toll Free at 1-800-4PA-8477.
