Tulsa police may have a suspect in the homicide of a Will Rogers High School student last Saturday. We're told that the victim, 18-year old Gabby Bledsoe, was home alone and was tweeting last Friday night, but her mom says the calls stopped getting answered a few hours later. "We are still looking at him as either to clear him or to focus on him. We don't know which way that's going to go," said Tulsa Police Sergeant Dave Walker. Gabby Bledsoe's mother, Lacrecia Bledsoe, believes that someone Gabby used to date broke into the house early last Saturday while Lacrecia Bledsoe and Gabby's sister spent the night with a family friend. We're told that's when Gabby grabbed a kitchen knife, but the intruder used it against her. Lacrecia Bledsoe said, "She was tiny and I'm pretty sure whoever did this was bigger than her, stronger than her. You could have pushed her down...and she would have run away from you. She wasn't going to harm you." Police say that there were no signs of a struggle. Police told the News On 6 that they have the man's clothing and car and that they are getting warrants for fingerprints and DNA. Gabby's funeral is Saturday.
