Regola's 16-year-old son returned home Friday night, but it is unknown whether the teens saw each other.
State police say that forensic tests will take about two weeks to determine whether the boy committed suicide, accidentally shot himself or was shot some other way.
Police say that no suicide note was found at the scene.
Videos on WPXI say State Police are calling the death suspicious. They are also reporting Regola's kid came home about 10:30.http://www.wpxi.com/news/9571786/detail.html
