From the Lawrence Daily Journal-World for April 10, 1973:

• In a unanimous, history-making vote today, the Lawrence City Commission elected Nancy Hambleton as the first female mayor of the city. Hambleton, 48, who had finished first in both primary and general city elections two years ago, said that she hoped she could encourage more women to become active in city politics.
• Investigators today were no closer to finding a solution to the mystery of a triple homicide near Ottawa two weeks previously. The steering committee of the Douglas County Reward Fund, acting on the recommendation of Douglas County Sheriff Rex Johnson and Lawrence Police Chief Richard Stanwix, were offering a cash award of $1,000 for any information leading to arrests and convictions in the case. The deaths of Mrs. Hazel Avery and Gary Longfellow, both of Lawrence, and of Steven Avery, Iola, remain unsolved as of 2013.
• It didn’t feel much like April weather in Lawrence this morning as temperatures plunged to a 27-degree low, tying the date’s record low set in 1952. Although the frost melted quickly this morning, many orchards had suffered damages.
