Friends and family mourn victims of Pennsylvania shooting

Relatives and friends mourned Sunday at a memorial outside an

Erie, Pennsylvania home, where authorities say a man killed

eight people before killing himself.

Julius Windham's 1 year-old daughter Amarianna and her

mother, Angelina, were among those killed.

He said, "it's crazy how a person could do something like that, so tragic

like that to innocent children. Words can't even explain what I'm going

through right now. But I gotta be strong for my community,

you know what I saying? My family, my daughters, my sons, everybody."

Mourners added flowers and candles outside the home

as longtime friends remembered the victims and struggled

to understand the violence.

Investigators recovered video and audio evidence indicating shots

were fired inside before two distressed women arrived

and pounded on the door.

The gunman emerged and shot the women, before returning inside.

Authorities have not disclosed a motive and the investigation continues.
