The cause of Eddie Guerrero’s death hasn’t been officially released as far as I know but his widow Vickie did issue a statement about it…
The widow of World Wrestling Entertainment superstar Eddie Guerrero told the organization Tuesday that preliminary tests show he died of heart failure.
“It was from his past — the drinking and the drug use,” Vickie Guerrero said on http://www.wwe.com. “They found signs of heart disease. [The medical examiner] said that the blood vessels were very worn and narrow, and that just showed all the abuse from the scheduling of work and his past.”
If I remember correctly Eddie is being buried today, if he hasn’t been already, in a private ceremony in Arizona.
If you go to WWE.com they are selling Eddie Guerrero commemorative t-shirts for $20 with all proceeds going to the Guerrero family.
Vaya con Dios Eddie.
