I couldn't find much, but his name, name of his show and his co-worker name are clasicly coded. Date of birthday and significance of the place and time of incident remains a mystery

His name : Luis Manuel Medina = 74
Co-worker : Leonidas Martinez = 77
Mr Martinez = 137 

Medina and Martinez had been hosting the show "Milenio Caliente" - Hot Millennium 
Milenio Caliente = 74
radio hosts = 74
Hot Millennium = 66

I found some photos

This is how his room in witch he stream looks like in all of his videos.
