“I have a gun. Give me all your money or die. Any funny stuff and I’ll get you before they get me. Put money in black zipper bag.”

The woman did not display an actual gun, but held her hand in her long dark blue coat with gold buttons as if she had a gun. Ava put about $33,000 (equal to $186,896 in 2014) into the bag and after the robber walked out, she activated the bank alarm and alerted other employees.

Butler was later arrested by FBI agents responding to an anonymous tip, and charged with being an accessory to the robbery. They caught the robber, Vickey Stevens, in North Carolina on May 4, 1972. A man was also being sought. In his house, federal agents found more than $30,000 from the robbery. (Left) Marina City Bank, circa March 1973, from across State Street. Photo by Mike Chunko.

By the end of 1974, Marina City Bank would outgrow Marina City and move its main banking facilities to the Old Republic Building on North Michigan Avenue. Marina City would be a full-service but remote location.

The bank was a footnote in Chicago history in February 1978, when it was disclosed it had $2 million in deposits from the Teamsters Union pension fund. The fund was in trouble for having $178 million in shaky loans.
