Boy Killed By Step-Father Who Then Commits Suicide

Early morning gunfire ended a deadly, hours-long stand-off in Lewisville overnight.  It started Thursday evening when a teenage boy was shot at a home on High Meadow, just off I-35 near Valley Ridge.  Then the shooter holed up inside the home where a police SWAT team set up to negotiate.  But the talking ended seven hours later when the man shot himself, ending what police believe was a domestic conflict.  Neighbors believe the gunman shot his teenage step-son around 7:30 p.m. Moments later, the boy's mother escaped and pleaded with neighbors to call for help.  Lewisville police captain Jay Powell says the SWAT team was able to speak with the step-father by phone but he would not emerge from the home.  Then, around 2:30 a.m. today officers heard a single gunshot.  When they went in, they found both bodies.
