First we'll get to the NBA star using social media to find the killer who brutally murdered his aunt. The plea from Matt Barnes of the L.A. Clippers touching hundreds of thousands on Twitter and instagram. ABC's Abbie Boudreau sat down with him for an interview. Reporter: Basketball star Matt Barnes says he feels compelled to use his platform as a professional athlete to help police hunt down his aunt's kill even if it means turning to Twitter. He's the NBA star who's now using his celebrity status to launch what could be called the million tweet manhunt. Los Angeles clippers small forward Matt Barnes pleading with his hundreds of thousands of Twitter and instagram followers to keep an eye out for this man, Michael Williams, the prime suspect in the murder of Barnes' aunt. Having the platform that I had I want to speak out on social media and got some of my other friends to repost it and really have the whole city of scream on the lookout for this guy. Why not let police investigate. When it's your family you feel like you can do more. You want to do more. Reporwilliams, not just a suspect, also the husband of Barnes' aunt and police consider him extremely dangerous. That's why Barnes took the unusual step of taking to social media with this post "This dude stabbed my auntie in the necklace week and left her for dead on the sidewalk." Then asked anyone with a lead to contact the police. In her last moments she was trying to speak and say who did it and what happened and you know she literally lost her voice. Reporter: His aunt and Williams were staying at a friend's house on the morning of July 8th when he says the friend rushed outside to find Hoover frustrating for her life and Williams -- Her husband was gone and she kept trying to say -- What do you think that mean. Without looking too far into it it's probably Michael, her husband. Sacramento police chief confirms with ABC news that Michael Williams is their one and only suspect. I have some frustrated officers here because they thought they would be able to get this guy right away but we'll get him. Reporter: He feels they're closing in on the suspect and saying in part thanks to Barnes. He has a following here in Sacramento. And having his name attached with this and helping in this investigation will help us actually solve this matter. As for Barnes as he gears up for the clippers' training camp in a few months he promises to keep fighting for justice and his beloved aunt. And her unfortunate passing I'm hoping to be her voice and, you know, her eyes and ears and really try to help in any way possible. Police say they believe the suspect may still be hiding out in the Sacramento area and if you have any information that could help bring this manhunt to an end you're asked to contact the Sacramento police right away.
