PENNSAUKEN, N.J. -- More details emerged Tuesday about the 72-year-old woman found slain inside her home Monday in Pennsauken.

It's not the first time the woman and her family have been the victims of a violent and deadly crime.

The family believe they know why she was killed, NBC 10'S Jamison Uhler reported.

Friends and relatives said Ty Nguyen would open up her home to anyone who needed help. She lived in the home along with her two grandchildren and three tenants.

Relatives also said she stashed a large amount of cash inside the home, and they believe whoever killed her knew that.

"Somebody wanted to take money from her," one family member said.

Asked if he believes it was somebody she knew, the man answered, "I would say, 'Yes.'"

That's one of the theories family and police believe may have been behind the killing.

The 72-year-old was beaten to death in her kitchen. Police said it was done with a heavy object.

Police said there were no signs of forced entry or obvious signs of robbery.

But as Nguyen's family returned to the crime scene Tuesday, they told Uhler that keeping money stashed inside the home to not rely solely on banks is part of the Vietnamese culture.

Police would not say if any money was missing.

"A lot of Vietnamese elderly or their families get victimized because they hold a lot of money, cash, in the house," the family member said.

Relatives and friends said Nguyen survived the Vietnam War, came to this country and let fellow Vietnamese immigrants stay at her home while they got on their feet.

"She's nice. She's so sweet with people. She's so sweet," one woman said.

She also took care of her teenage granddaughter and grandson.

Nguyen was placed in charge of the children after a wild robbery in Camden back in 1995. It was then that Nguyen's son and his wife were murdered, and Nguyen's granddaughter -- 4 years old at the time -- was held hostage before a police sniper took out the gunman.

Now, tragedy has struck the family once again, only months before the victim was going to move back to Vietnam.

"She stayed here in the U.S. for the kids, to raise them up and make sure to put them through school. Then, after that, she would retire and go back to her homeland in Vietnam," said the male family member.

Prosecutors said they have interviewed everyone who lived inside the home but do not have any suspects.

In the meantime, the family is working to get Nguyen's family back to Vietnam so she can be laid to rest, Uhler reported.
