Lattice Porter said her sister was a hard-working mom of four kids, three of whom she adopted, and worked as a detention officer. She also said she doesn't think the murder was random.
"It's a tragic missing link," Porter said. "It's something that did not need to happen."
"We're no closer today than we were 26 years ago," said Darren Burch from Silent Witness. He said there were no signs of forced entry.

"No matter how small the information, that's what we need them to call in on," Burch said.

"As time goes on, you have to kind of come to grips with the situation but it doesn't mean it makes it any easier," Brown said.
A new detective has been assigned to the case. If you have any information on this, contact Silent Witness at 480-WITNESS. The reward is up to $1,000.
