It's a file that's not in the "cold case" pile just yet.

Detectives are following new leads in the murder of Gainesville teen Sebastian Ochsenius.

The 16-year-old was shot to death inside his house in June of 2010, and his killer is still at large.

On Friday, a group of Ochsenius' friends began setting up a fundraiser, "16 hours for 16 years," a lacrosse marathon, that starts Saturday morning, and benefits the Sebastian Ochsenius scholarship foundation.

"16 hours for 16 years" will be Saturday from 7 A.M. to 11 P.M. at Buccholz High School in Gainsville.

If you're not up for 16 straight hours of lacrosse, there's a silent auction going on throughout the day.
