Beaten
TDoR list ref: tdor.info/29 Aug 2005/Mikey Vallejo-Seiber

Mikey was beaten to death by his father, Alex Mendoza, who had repeatedly called him a "sissy”.
Mendoza also often slapped his son in an effort to "toughen him up,” and urged him to beat up an Elmo doll. Mikey Vallejo-Seiber died in a local hospital from internal injuries sustained from being kicked, punched, and dropped on his head while in Mendoza’s care.
Mikey's mother Pamela Seiber pleaded guilty to child endangerment and - two days after what would have been Mikey's fourth birthday - was sentenced to 6yrs in prison for failing to protect her son.
Mendoza entered a plea of not guilty and was sentenced to 25 years to life.
Editors note: Although we will obviously never know whether Mikey may eventually have identified as trans, it is fitting that he be remembered here.
