NORWALK — Sentencing was delayed Wednesday for a La Habra man facing the death penalty for two gang-related murders in Whittier, including one in which he fatally stabbed the wrong man, authorities said.

A jury recommended the death sentence in January for Gabriel Alexander Ronquillo, 39, for the 2004 mistaken-identity murder of 47-year-old Gary Frausto, as well as the 1999 slaying of rival gang member David Borunda, 23. He was convicted of the killings in December in Norwalk Superior Court.

His sentencing was initially scheduled for Wednesday, but was postponed to March 15, court officials said.

Ronquillo was arrested following the most recent killing, after his would-be getaway car failed to start, investigators said.

In Frausto’s killing, authorities said, Ronquillo was following an order from the Mexican Mafia to kill another man, Frausto’s brother, but stabbed Frausto to death by mistake when he answered a midnight knock at the door.

In addition to the two murders, a jury also found true special allegation of multiple murder, murder for the benefit of a street gang, murder by an active gang member, use of a deadly and dangerous weapon and principal discharge of a firearm causing death, officials said.
