Police say Young stabbed a 58-year-old man at the Colesville post office because he thought that the man had cut in line ahead of him.

In fact, the victim had been asked to step aside to finish his paperwork, and a postal employee had later signaled for him to return to the front counter, police said.

Young walked out of the area and waited in the post office’s vestibule, police said. When the victim headed out as well, Young stabbed him multiple times, according to police.

As the men struggled, two postal workers came out, and at least one of them sprayed the assailant with pepper spray. The man fled.

“It worked,” said Tom Ouellette, public information representative for the United States Postal Inspection Service.

“The police are crediting them with preventing further injury to the victim, other customers and the other employees.”

Police said witnesses gave officers a description of the suspect’s car, and Young was found about a mile away at New Hampshire Avenue and Route 29.

The victim was taken to the hospital and is in serious condition, but his injuries were not considered life-threatening, authorities said.

“It’s a shame. Nobody likes waiting in line, but to have a dispute like that escalate to physical violence is exceptionally rare,” Ouellette said. “Post offices are one of the safest places to conduct business.”

The post office is located at 13217 New Hampshire Ave.

Young is set to have a court hearing Friday afternoon.
