The uncle of Lyle and Erik Menendez, who opposed their release from prison, has died. He was 91. Anamaria Baralt, a cousin of the Menendez brothers, confirmed Milton Andersen’s death on Sunday. She announced, via TikTok, that Andersen had died from cancer. This is following an obituary that was shared by the Thompson & Kuenster Funeral Home in Illinois on March 4. While the brothers’ cousin is in favor of their release, Baralt told fans that no one should rejoice that Andersen had passed. She said that she felt “great empathy” for the boys’ uncle who lost his sister Kitty Menendez in 1989 alongside her husband Jose Menendez, at the hands of the brothers. Andersen was the last of the living relatives who was advocating for Lyle and Erik Menendez to remain imprisoned. The boys’ uncle recently spoke against their release through his attorney Kathy Cady in 2024. Although the rest of the Menendez brothers’ family believe that they killed their parents because their father sexually molested them, Andersen maintained their reasons were motivated by greed. He wasn’t always alone in his assertion. Andersen’s late brother Brian joined him in testifying against their nephews in the death penalty phase of their murder trial in 1996.
