CLINTON TOWNSHIP, Mich. – 
Investigators were dusting for fingerprints at a murder scene they call brutal and bloody in Clinton Township.
A 47-year-old mentally-challenged mother and her 11-year-old mentally-challenged daughter were found stabbed to death Tuesday inside their apartment at Parkway Village.
"They couldn't have caused you any harm. They couldn't have done anything to you," said neighbor Latausha King.
Neighbors called Tina Geiger and her daughter Chrissy the dynamic duo.
"You'd see them everyday, walking to the store. They'd speak to us. We'd give them loose change," said neighbor Maurice Williams.
They had no car and walked everywhere, neighbors say. The highlight of their day was walking up to the nearby 7-Eleven for a grape Slurpee.
"Something as simple as going to 7-Eleven to buy a Slurpee, that made her day," said Williams.
Neighbors say they found it strange that for the past few days no one had seen the mother and daughter out walking. Police say the mother's caretaker alerted the apartment manager. He went to check on the two and made the horrific discovery.
Police say there was no sign of forced entry. Sources tell Local 4 the suspect knew Geiger and her daughter. Right now, investigators know who they are looking for and are trying to tack down the alleged cold-blooded killer.
"I do hope they catch whoever this is and put them where they belong, and that's away from anyone," said King.
