Derek was born in Mankato, MN on January 13th, 1973 to Sandi Drummer. He served our country through the United States Navy from 1991-1994 as an Airman Boatswain's Mate (ABH). Derek loved all things Navy and was proud of what he did for his country.

Derek had a larger-than-life personality and a heart full of compassion. He loved his family fiercely and believed in giving everyone the benefit of the doubt. His passions included music—especially Rammstein—coffee, cigarettes, and living life on his own terms. A devoted Minnesota sports fan, Derek cheered passionately for every team that bore the state's name.

Derek is survived by his mother Sandi Drummer, father Tom Maleitzke (Kathy), son Coel (Keisha), twin brother Damian (Erin), brothers Dustan (Mary) Dallas (Ashley), sisters Mollie (Chris) and Jennie (Jeremy), special cousin Tina (Chris) and step children Kalee (James), Timothy (Lou), and Darian. His heart carried ongoing love for his grandchildren Dean, Juniper, Ainz and Zico, many aunts, uncles, cousins, nieces and nephews and friend and ex-wife Jana.  He shared a special bond with his loyal canine companion, Kaiser.

A Ft. Snelling burial will be held on March 27, 2026 and Celebration of Life will be held at a later date.
