The 28 year old Vallum was a member of the Latin Kings street gang, and he stabbed and beat to death 17 year old Williamson back on May 30, 2015 at his father's home in George County, MS and buried her on the property.
Vallum was indicted for the murder of Williamson on July 29, 2015 and pled guilty to the heinous crime.
Vallum will be eligible for parole when he hits age 65, which won't be until 2053.
But we can now note that another murderer of a trans woman is locked up behind bars, and we'll be watching and waiting 3 years from now to ensure you stay there.
Continue to rest in power and peace, Mercedes.
