Princeton police in Collin County and the Texas Rangers are still investigating after a woman was found dead in her home last week.
Kelli Underwood, 46, was found last Wednesday evening after someone called for a welfare check. Initially police suspected suicide, but an autopsy indicates Kelli was murdered. Police will not say how she was killed.
"I would like justice for Kelli. She deserves that. She didn't deserve what happened to her. Kelli was very strong, Kelli had a huge heart. Kelli loved her family dearly,” said sister Amber Parker.
Family members said Kelli was a smart, hard-working single mother of three who lived alone in her Princeton home and worked for a local sheet metal fabrication company.
"Kelli was the type of person that wasn't afraid of much,” said sister Ginger Ambrose.
Police remain tightlipped about the investigation, but said the case is believed to be isolated and there is no immediate threat to the community.
Neighbors like Casandra Beamon said Wednesday they need reassurance.
"It's very scary to walk out the door and don't know what happened,” Beamon said. "This is a small community, this just never happens. So, I don't know if it was a friend or stranger or what, we don't know if she got broken into? And so, we don't know anything."
Princeton police have called in the Texas Rangers to assist in the investigation and they are also asking for the public call in tips to help solve this murder.
"If anybody knows anything, please come forward. We're trying to figure out now what type of reward is available but we're asking for somebody to please, please come forward,” Ambrose said.
Family members said Underwood’s funeral will be Thursday in McKinney.
