On the early morning of December 24, 2022, Jacob Keanu Campos Malena, 30, died after forcibly entering a home on Snowdon Avenue in Bakersfield. Malena, described as the estranged boyfriend of a woman living at the residence, was armed when he broke in. Inside the house a 30-year-old man, Tanner William Marlow, confronted him. Both men fired weapons and both were killed; the woman in the home was not injured.

Authorities identified the two men through the Kern County Coroner’s Office and the Bakersfield Police Department opened a homicide investigation. Family and friends said Malena was a father of four and that Marlow, known by the nickname The American Psycho, was an undefeated MMA fighter remembered as protective by those close to him. No arrests were possible because both principal participants died.

Does anyone have information about the events that led up to the confrontation or the relationships involved that could help investigators?
