The murder of a Lubbock family is still unsolved three years later.
Police found the bodies of Tammie Cooper and her three children inside a Northeast Lubbock apartment. Mahogany Jasmine Allen was 11 years old and twins Kadiece and Kasheem Allen were 9 years old.
The investigation has taken Lubbock police to California and to Dallas more than 20 times. Those leads turned up nothing, but there is still one man police want to talk with. Police are still trying to identify a black man they believe was the last visitor to the Cooper home.
Apparently, Tammie Cooper called the man "Butch" and allowed him into the apartment. Thursday NewsChannel 11 spoke with Cooper's mother, who says she thinks of her daughter and grandchildren every day.
"It's not easy sugar. I always think about them and want to know who did it," Mary Cooper, Tammie's mother said.
Three years later, Cooper, Tammie's mother still does not have answers, nor do Lubbock police.
LPD Detective Rey Martinez tells NewsChannel 11, "All the time that has gone by, to be perfectly honest, it doesn't really seem like we've gotten a lot of cooperation from just the people who knew her."
Tammie Cooper, 45, and her children were living at Windcrest Estacado when they were murdered. The complex has since been renamed Madison Park. Detectives say the victims were found throughout the apartment and had been viciously attacked.
"It was really one of the most brutally violent murders that I've ever seen and I've been in this business for a long time," said Detective Martinez.
Autopsy results would later show the family died from blunt force trauma and the use of a sharp instrument.
Not long after Cooper and her children were found brutally murdered at their home Lubbock Police issue a flyer asking for information about this gruesome crime. Information, that has led them to the Dallas area.
"As the investigation progressed it also became more difficult because most of the people and work we needed to do were in the Dallas area," Martinez added.
Detective Martinez says they have been to Dallas more than 20 times investigating leads that have turned up nothing. He says he hopes people, "Talk about it in the community and maybe somebody will come forward and give us some of the right information."
Information that could help ease Mary Cooper's pain.
"Some days I look at their pictures and it's hard for me," Mary Cooper said.
Again, police are looking for a black man apparently named Butch. They believe he may be the last person to see the Cooper family alive.
