HIGHLANDS, Texas -

Investigators say a woman found dead in an east Harris County house fire last week was stabbed to death.

Harris County Sheriff's Office says they are looking for information that might lead them to a suspect or suspects in the case.

On the morning of Dec. 13, deputies were requested by the Highlands Fire Department to respond to a house fire in the 800 block of Clear Lake Rd. with possible people trapped inside. After the fire was extinguished, deputies say the remains of a white female were located inside the residence.

The victim was later identified as the homeowner, 72 year-old Caroline Suellen Stagner, who went by Sue.

Stagner, a mother and grandmother, lived alone.

The Harris County Institute of Forensic Sciences conducted an autopsy on the victim and determined that the victim died as a result of several stab wounds prior to the fire.

"As the day progressed on Friday it went from my mom's house is on fire to my mom's gone to somebody's hurt her," said Donna Hawks, the victim's daughter. "Somebody broke into the house and hurt my mother."

The family now believes that someone set fire to the house to possibly cover up a crime.  They have no idea who would have done such a thing or why.

"She had no enemies," Hawks said. "My mother worked here in Highlands for 36 years for the water department.  She loved everyone and everyone loved her.  She knew everyone.  It's just unbelievable that it would happen in this little town."

Highlands residents told Local 2 they saw Harris County Sheriff's deputies driving around town all day on Monday.  They were spotted at a local business and also at a home located on North 9th street, about one block from Stagner's home. 

Neighbors said investigators took two people into custody, possibly for questioning. Family members said they know of no arrests, at least not yet.

"I'm praying this is it," Hawks said.  "We want these people off the street."

Anyone with information about the murder of Mrs. Stagner is asked to call the HCSO's Homicide Unit at 713-967-5810, Crime Stoppers at 713-222-TIPS (8477), or submit a tip via iWatchHarrisCounty.
