Henning allegedly stole hydrocodone from someone and removed medication before putting the bottle in the evidence locker. He was being held Wednesday on $175,000 bail at the North Central Regional Jail.
In December 2011, former Shinnston officer Kevin Junkins Jr. was charged with possession and intent to deliver hydrocodone, obtaining a controlled substance by fraud and other offenses. He's also charged with stealing money from the evidence room.
City Manager Debra Herndon told The Associated Press that municipal officials were saddened and distressed to learn of the arrest of Book, who was with the city for 35 years, many of them as chief, and was considered "a staple in the community."
However, he hasn't worked for Shinnston since 1998 and is now a private citizen, so Herndon said she couldn't comment further.
"When the city suspected some wrongdoing on the part of Officer Henning," she said, "we did contact the sheriff's department, and we certainly have fully cooperated with the investigation."
The Shinnston Police Department is down to three certified officers, including the acting chief, and Herndon said two newly hired men will start their 18-week training at the police academy next week.
City officials have talked with Acting Chief Jason Carlson about changing the hiring process, Herndon said, and they're seeking advice from other departments and agencies. The city will also add a physical fitness component to its hiring criteria and ask the county for help with background checks.
"I think in the past, we've depended too much on references from other department," Herndon said, "and that can be problematic because sometimes people just want to get rid of a troublesome employee, and they'll give you a good reference."
