BUFFALO, N.Y. — "This situation was completely different than any one I've ever deal with before."

Reverend James Lewis III of Buffalo worked with Yvette Johnson's mother, Marlene Works, for years.

Yvette, 54, was shot to death, along with her 17-month-old grandson Kyree outside the family's Grape Street home during a party early Monday morning.

"We've known this family for a long time, so now it's getting close to home,” said Rev. Lewis, the trauma Chaplin at ECMC. “And this is one of the most insensitive, crazy tragedies that I've ever seen."

Yvette's brother, visiting from Atlanta, and her other son, Kyree's uncle, were also shot.

They were treated and released from ECMC.

The shooting "took me to another emotional level,” said Tina Sanders, founder of No More Tears. “A child was involved, a baby. Who gives anyone the right to just come anywhere and take someone's life

No More Tears is one of six organizations that comprise Buffalo Peacemakers.

She spent part of Tuesday with Yvette's mother to provide support during this difficult time.

"That's her daughter and her great-gran,” Sanders said. “And you know you never plan to bury your children. You know? So she's grasping, but she's not grasping and you know the main thing is just to continue to keep her and the family in prayer."

In the meantime, police are following up on a number of leads, as people also share information on social media. The person or persons responsible for the shooting are still at large.

Police do not believe it was a random act of violence, and are increasing patrols in the area.

"With an atrocity of a 17-month old child being killed, I think that strikes at the heart and minds of just about every person, so cooperation tends to be better in cases like that,” said Buffalo Police Captain Jeff Rinaldo.

It's that cooperation Lewis hopes will spur change.

"If you see something, say something. This entire community ought to be saying, enough is enough. This is so tragic it ought to change the rest of this summer for the city of Buffalo," he said.

Anyone with video or information about the shooting is urged to call the department's homicide division or the Buffalo police confidential tip line at 716-847-2255.
