Police have arrested a 36-year-old man they suspect robbed a Medford convenience store at knifepoint last week.

Medford officers arrested Anthony James Blank at about 1 p.m. Monday following an investigation into the April 5 incident at the Crown Market, 1112 Progress Drive. He has since been lodged in the Jackson County Jail on $250,000 bail, according to jail records.

Detectives suspect Blank of entering the Crown Market at about 4:30 p.m. Thursday and menacing the on-duty clerk with a folding knife after presenting her with a note.

The suspect, who wore a dark-colored, hooded sweatshirt, was caught on camera, with part of his face exposed beneath the sweatshirt’s hood.

Police shared a still image of the suspect, and a person came forward shortly afterward who identified Blank as a suspect, police said.

“Additional video surveillance in the area at the time of the robbery played a role in positively identifying the suspect,” a Medford police news release said.

Blank was believed to be staying at various motels around Medford. Police caught up with him in the WinCo parking lot Monday afternoon, where they arrested him without incident.

Detectives are still investigating two additional robberies where convenience stores were the target.

“We don’t think (Blank) is going to be responsible for those other two robberies,” said Lt. Mike Budreau. “We’re still actively looking for suspects in both of those cases.”

The first of the two robberies took place at 9:48 a.m. Feb. 21 at the Peach Street Market. In that case, the male suspect was heavily covered head to toe. The man reportedly jumped a counter with a knife in hand, but the clerk on duty resisted. A tussle ensued, and she attempted to run away. The man followed and pushed her down. He left with no money. The man is described as 5-foot-11 with a skinny build and blue eyes. He wore red and white shoes, and a black or dark-colored sweatshirt with white drawstrings.

The man in an April 1 robbery at the Woodland Heights Market on Prune Street is described as 5-foot-9 inches, also with a thin build. Like the Peach Street robbery, he was covered, wielded a knife and hopped the counter. The clerk on duty in that case was compliant, and the suspect fled with money.

Anyone with information about the Peach Street or Woodland Heights market cases is asked to contact Medford police at 541-770-4783.
