The Frederick County Sheriffs Office is still investigating the death of a local 17 year old.

Investigators are working on creating a sketch of the two people involved in the shooting and killing of Rhett Goldizen.

Captain Al Sibert says they're still looking for two men who showed up at Monastery Ridge Road in the middle of the night a few weeks ago.

The two men allegedly got into an argument with the teen's father, Steve Goldizen, at the front door and shots were fired.

Sibert says, in addition to the sketch, they're working on getting the make and model of the car the guys were driving.

"Even if it's somebody that you don't expect, but you know somebody might have left town or went out of town for a day or two immediately after the homicide. That information may be helpful, it may be the reason they left town, because they were involved in something. Maybe they know something about the people that were involved in it and they're scared themselves." He says they believe they have a good handle on what happened that night, they just don't know who did it.

Sibert says based on how fast the car got away in the night, it's possible there was a third person involved who was still in the car but that is just speculation.
