“One thing we want to stress is that he is armed and is extremely dangerous. Do not approach him, but immediately contact your local law enforcement agency,” Sheriff Pat Burnett said at a Monday press conference.
Burnett was referring to 31-year-old Donny Lee Greenhow, who has been named the suspect in the double slaying of Peter Shick, 74 and his wife Latricia, 55.
A capital murder warrant has been issued for Greenhow, who police believe has stolen multiple vehicles in the past week.
Burnett, Sheriff's Detective Sam Mayer and Van Zandt County District Attorney Chris Martin released new details in the homicide and Greenhow.
Martin said Greenhow has been in trouble with law enforcement in the past, including an aggravated assault with a deadly weapon case as a juvenile.
He said investigators believe, during the past month, Greenhow has stolen several vehicles and multiple weapons from various friends and family.
Mayer said Greenhow knew the Shicks, and the crime was not random.
Shick was found dead of gunshot wounds in the couple's bedroom in the singlewide mobile home on County Road 4812. Mrs. Shick was found in the kitchen of the home, Mayer said.
Burnett said the couple may have been dead up to nine days before they were discovered.
Investigators said they yet have developed a clear motive for the homicides, but said Greenhow recently had bounced from location to location with family and friends and had stolen vehicles, money and numerous guns during the past month.
Mayer said they were obtaining a subpoena to gain information from Greenhow's Facebook page, because they believe he has been using it to reach out for help from family and friends.
Martin said investigators knew Greenhow was in Waco early Wednesday, but they have no idea where he may be at this time.
He said Greenhow showed up at a friend's home in Waco, and the friend asked where he got the pickup he was driving, which he is accused of stealing from the Shicks at the time of the homicides.
“He told the friend that the truck belonged to someone he knew. The friend said he had to go to Nashville, Tenn., and asked Greenhow if he would mind house sitting,” he said.
Authorities are concerned Greenhow will commit other crimes to stay ahead of police.
“We don't know what he will do, but he is evidently capable of double homicide,” Burnett said.
Burnett said he hopes Greenhow will see his picture in the newspaper, on television or hear his name on the radio and turn himself in without further incident.
Greenhow, 31, is described as 6-foot-2, about 170 pounds with blonde hair, blue eyes, medium build, a scar on his upper right arm and forehead and a tattoo on his upper right arm.
