Authorities recently released a new cache of records in the death investigation of Gene Hackman and Betsy Arakawa — including a series of heartfelt notes the couple left for each other, revealing the close-knit nature of their relationship even as Hackman's health declined amid a battle with Alzheimer's.

A batch of letters between the couple was released as part of the investigation into their tragic deaths earlier this year

Gene Hackman and wife Betsy Arakawa's love was on full display throughout their home at the time of their deaths. In photos released by the Santa Fe County Sheriff's Office, several handwritten notes were scattered around the house where Hackman and Arakawa's dead bodies were discovered in February.
