March 1 marked the 90th anniversary of the kidnapping of Charles Lindbergh Jr. – the 20-month-old son of aviators Charles and Anne Morrow Lindbergh.

The kidnapping was one of the most infamous crimes of the 20th century. It happened on March 1, 1932, in Hopewell Township. The baby was taken from the Lindbergh home for ransom.

Hopewell police and the New Jersey State Police conducted an extensive search for the boy. His remains were found the following May.

Richard Hauptmann, a German-born carpenter was ultimately convicted of the abduction and murder of the Lindbergh baby. He was executed by electric chair in 1936.

The New Jersey State Police Museum and Learning Center has several historical artifacts from the investigation, including the electric chair used to execute Hauptmann. The museum is open Monday through Friday from 9 a.m. to 3 p.m.
