Family And Friends Say Goodbye To Christina Grimmie

MEDFORD, N.J. (CBS) -- Christina Grimmie may not have been physically present, but her voice, her images, her spirit, filled the room at Fellowship Alliance Chapel in Medford, N.J.

Hundred came out for a public memorial honoring the singing sensation who was shot to death last week after a show in Orlando.

One by one, memories of a young woman, whose life was cut far too short, came rushing back on those who knew her best.

Heart-wrenching moments from Christina's brother Marcus, who was there when she was killed and reportedly jumped on the gunman to detain him after the shooting.

"When the gunman came, he was very quick," her brother said. "It happened so fast, but her arms were open and the way she worded it was she saw Jesus next so, her arms were open for him and that's how she treated everyone she knew. Her arms were open to them at all times."

Finally, Christina's heart-broken parents addressed the crowd. Her mother kissed her daughter's picture inconsolable in her grief, still asking why.

"It's just so much," her mother said. "The last time I saw my daughter was on my birthday. I always told her I loved her. I always told her to put God first. When Christina went home to be with the Lord Jesus, I said 'I'm not mad. I'm not mad. I'm not mad,' but I want to know why."

That is a question that still haunts the Grimmie family and even authorities. No motive has been announced for the shooting.
