March 17, 2021 Waterloo, Ia (AP) — An Iowa man awaiting trial on an attempted murder charge has been charged with killing another man during a robbery. The Waterloo-Cedar Falls Courier reports that 32 year old Robert Lee Williams Jr. of Waterloo, was charged Tuesday with one count of first-degree murder in the death of 49-year-old Vincent Hemenway. Authorities allege Williams was part of a group of men who approached Hemenway and his friends on Aug. 15 while they were working on a vehicle inside a garage and asked to borrow a lighter. Hemenway volunteered his lighter and then resisted when one of the suspects attempted to walk away with it. At that point, someone opened fire, striking Hemenway.
