'Everybody' Loved Them: N.J. Native, 2 Daughters Were Triple-Murder Suicide Victims

Why? That's what Jennifer Lamb wanted to know as she dealt with the murder of her sister and her two young daughters last week in an apparent triple-murder and suicide.

Jacqueline (Jackie) Casey, 31, and her two daughters left New Jersey a few years ago. But she and her family will always be remembered, her sister said.

And in Egg Harbor Township, Lamb and others were mourning and in tears as they tried hard to grasp the tragic situation.

"I sit here and go through all of your pictures with blurry tear filled eyes, I can't help but ask, Why!!" Lamb said on Facebook as tributes poured in Monday.

"Why something like this could happen to someone like you and those babies!!" she said. "You were so loved by so many people..you touched so many lives and had SO MANY loyal friends!!!"

Casey, who graduated from Egg Harbor Township High School in 2004, and who had the maiden name Facciolli, was identified as one of four people found dead last Tuesday in a triple-murder suicide in Morris, Oklahoma, according to authorities.

Casey was killed along with Andrew Lyle Casey, 30, and her two daughters, Anna Casey, 6, and Lilly Casey, 1, Amy Elliott, spokeswoman for the Oklahoma Medical Examiner’s Office, told Patch.

Authorities declined to identify Andrew's relationship to Jackie, saying the matter is under investigation.

The Okmulgee County Sheriff's Office said the tragedy took place sometime before 9:12 a.m. on Feb. 7, when authorities received a phone call reporting the deaths.

Deputies responded to a home in Morris and discovered the bodies of a man, a woman and two children. The initial investigation revealed that there was a "disturbance which resulted in an apparent triple-murder and suicide," the sheriff's office said.

The matter is under investigation. A motive for the killings has not been released.

A GoFundMe.com page, meanwhile, has been set up for Jackie's family as they arrange services, and the page has already raised more than $21,000.

"As many of you already know Jackie and her two beautiful babies (Anna and Lily) were taken away from us way to soon by a senseless act," the page reads. "We would like to help my mother with the cost of bringing them home and having a memorial service for her friends and family to pay their final respects. Any help is greatly appreciated. Please' Share' even if you cannot make a donation. <3."

Lamb, meanwhile, thanked people for contributing to the GoFundMe page, even as she continued to wonder aloud why anybody would take her sister's life when she gave so much to others.

"I shouldn't have to be doing this...we shouldn't have to be doing this!!," Lamb said. "I shouldn't have to say good bye to my little sister and my nieces!! I love you all so much and just want you back!!! Forever and always!"
