From the July 6, 1896 Brooklyn Daily Eagle:

“The officials of a company which makes a feature of insuring the lives of animals notified the management of Glen Island to-day that they would not pay the policy on the life of Franko, the monkey which committed suicide yesterday. They claim the suicide clause holds good in this instance the same as in the case of a man. It is claimed that Franko deliberately hanged himself and that back of the sad affair is a love story of strong interest which goes to show that Cupid darts can play havoc in a monkey’s cage as well as elsewhere. Franko was desperately in love with a female monkey in the same cage. Last week he was removed to another cage and suicide followed.”
