Heather Nabil Mattia was 22 and a co-owner of the Granada Liquor Store in El Cajon when she was killed on March 1, 2006. She and a co-worker, Firas Eiso, were closing the store when two men, Jean Pierre Rices and Anthony Miller, forced them back inside and fatally shot both victims in the back of the head during a robbery.

Investigators arrested Rices and Miller. Rices pleaded guilty to two counts of first-degree murder and admitted to shooting Heather and Firas. He also pleaded guilty to attempted murder for slashing a jail guard with a knife fashioned from a razor blade and to charges tied to other El Cajon robberies; the decision on whether prosecutors would seek the death penalty was under review. Miller was scheduled for trial and had told police he left the store before the shootings; he faced a maximum penalty of life without parole.

The killings devastated the El Cajon Chaldean community and the victims’ families. Does anyone have memories of Heather, where she worked, or information that could shed light on the case?
