Carla and I had the pleasure of meeting Angelo at Ellora's Cave Romanticon last year and I remained in contact with him over the last year. We became friends and he was gracious to volunteer to be my long-distance personal trainer, even when I told him I gained 2 pounds he told me it was no big deal and to get back on track.
You will be missed my friend by all of us who loved your smile, charm and your caring for those around you.
Update: Ruben's family has setup a Facebook Page in Memory of this great guy http://www.facebook.com/annette.r.stone?ref=tn_tnmn#!/pages/In-Memory-Of-Ruben-Dario-Riguero-Brito/279284965522566
They also released a statement to the press which can be found here
