PHILADELPHIA (AP) — A funeral is set for a Philadelphia community activist gunned down during an attempted carjacking while his 2-year-old daughter sat in the back seat.

The funeral Mass for 38-year-old Gerard Grandzol is set Wednesday at the Cathedral Basilica of Saints Peter and Paul.

Police believe 16-year-old Marvin Roberts shot Grandzol, while accompanied by his brother, 21-year-old Maurice Roberts. Both have been jailed on homicide charges and Marvin has been charged as an adult.

Police say that happened when the brothers accosted Grandzol outside his home Thursday night, took his wallet and demanded his car keys.

Grandzol is also survived by his wife and another daughter who was born in July.

Online court records don't list attorneys for the Roberts brothers.
