POTTSBORO, TEXAS -- Quiet Scott Hill Road near Pottsboro became a crime scene Monday night, when 70-year-old Marlene Cannon was found in her home, bloody and brutally beaten.
She died two days later due to her injuries.
The Grayson County Sheriff's Office and the Texas Rangers are investigating, as her attacker remains at-large.
"We've taken some evidence to the crime lab in Garland that they're going over for us at this time and we are currently building a list of suspects," Lt. Rickey Wheeler with the Grayson County Sheriff's Office said.
"It's kind of a tragedy that crap like this has to happen in a small town," neighbor Loren Wood said.
Wood didn't know Cannon personally, but says he saw her around town and sympathizes with her as a fellow senior, especially vulnerable to an attack.
"Hell, I've got gray hair, so did she. You know what I mean? I mean, people look at us people like that," Wood said.
While it's not confirmed by investigators, people we spoke to believe Cannon knew her attacker.
"Or else they wouldn't have, she wouldn't have let them in the house," Wood said.
That scares neighbor Julee Kendall.
"It could be one of your neighbors, and that's absolutely terrifying 'cause it makes you feel like you think you know somebody, and then you may not know them at all," Kendall said.
Kendall says they usually only see petty crime here, not murder.
"A few car break-ins, property stolen from houses, but never anything that bad. No one ever really seriously injured," Kendall said.
Officials say when they do catch Cannon's attacker, they'll pursue the maximum sentence.
"It's going to be a murder charge, so they'll be looking at life," Lt. Wheeler said.
Authorities are asking anyone with information to contact the Grayson County Sheriff's Office.
Cannon's obituary says she was a simple yet sophisticated woman, who was one of a kind.
Her memorial service is this Saturday at 2 o'clock at the Church of the Resurrection in Sherman.
