EAST MILLINOCKET, Maine — A Sherman man was charged today with attempting to rob at knifepoint a Main Street pharmacy last month, police said.

Travis Robinson, 23, was charged at about 11:30 a.m. with armed robbery, Police Chief Garold “Twig” Cramp said. Maine State Police criminal investigation division detectives assisted town police in the arrest because it occurred in Sherman.

Robinson, who has no prior criminal record, is charged with entering Davis Pharmacy, 59 Main St., at about 1:40 p.m. Sept. 15, displaying a knife and demanding certain prescription drugs, Cramp said.

“I think at that point the suspect panicked,” Cramp said Thursday. “He stood there for a minute, then took off without getting anything.”

Physical evidence collected at the scene helped tie Robinson to the crime, Cramp said.

He declined to comment on what the forensic evidence was because the case is ongoing. Police were collecting and searching for more evidence tying Robinson to the crime on Thursday afternoon, Cramp said.

“Everybody did a really good job at the crime scene with evidence and with the follow-up,” Cramp said.

Officer Cameron McDunnah, Cramp and Millinocket police Detective John Glidden handled the investigation or assisted at the crime scene, Cramp said.

Robinson was being held at the Penobscot County Jail in Bangor as of this afternoon, a jail official said. He is due in Penobscot County Superior Court tomorrow morning.
