NEW YORK (AP) - Prosecutors say a man with alleged mob ties who was fatally shot at a Bronx McDonald's drive-thru last year was tracked using a GPS device hidden on his car.

Assistant U.S. Attorney Lindsay Gerdes said in court Friday that investigators linked the device to some of the five alleged Bloods gang members charged in 71-year-old Sylvester Zottola's death.

Zottola was killed Oct. 4 while in his car, waiting for a cup of coffee outside the fast-food joint in the Bronx. Authorities say he had ties to the Bonanno crime family.

Prosecutors are weighing whether to seek the death penalty.

Gerdes says the suspected hitmen tracked Zottola for five days before the ambush. She says they also plotted to kill his son, Salvatore. The 41-year-old survived a July shooting.
