The bizarre behavior of a man who attacked tellers at U.S. Bank with a hammer last week was revealed Tuesday in court as the irate would-be robber was bound to the grand jury on 10 criminal counts.The defendant, Arlin Pinkard Jr., was bound to the grand jury on three counts of domestic assault, two counts of aggravated assault, and single counts of resisting arrest with a deadly weapon, reckless endangerment with a weapon, vandalism, especially aggravated burglary, and distributing or delivery of any substance as an act of terrorism or as a hoax.The last count, investigators say, came as the result of Pinkard pouring a white substance on the counter of U.S. Bank when the shirtless man walked into the Chancery Street business last week and began shouting threats before jumping the counter and grabbing a hammer from a construction zone in the bank.“He walked in and sprinkled the powder on the counter, saying something bad was going to happen,” said McMinnville police investigator Todd Rowland. “He never said what was going to happen, just that something bad was going to happen.”While authorities have sent the white substance for analysis, they believe the powder was actually meth. Other than being an illegal drug, they do not believe the powder presented any physical threat to the bankers as would have something like anthrax or other kinds of hazardous powders.
