There was a story on FNC last night on this; it is a state senator (don't know party, don't know name). HEre is what is on their web site regarding this:
Is a Pa. state senator to blame for the shooting death of teen neighbor Louis Farrell? 'The Lineup' investigates!
Apparently the senator's gun was the weapon used in the murder/suicide (not yet determined). I don't believe the senator's name was given. Its not much, but all I can find on this topic.
Thanks, Laverne.
