HENDERSONVILLE, Tenn. (AP) — Police in Hendersonville say a man died Sunday night after he broke into his ex-girlfriend's house and exchanged gunfire with the woman's son.

Police told WSMV-TV in Nashville (http://bit.ly/1mBog9h) that 36-year-old Brian Davidson of Charlotte forced his way into the home of Shawna Brush on just after 8 p.m.

After realizing Davidson was in the house, police say the woman's 18-year-old son, Connor Brush, grabbed his gun and exchanged gunfire with Davidson while the rest of the family escaped.
