Sheriff: Texas teen kills mom, 2 neighbors, then himself

McALLEN, Texas (AP) — A 19-year-old killed his mother and two neighbors before turning his gun on himself in a shooting that brought SWAT and various emergency vehicles to a rural area in Texas, authorities said Sunday.

The teenage boy was with Arthur Norton, 58, when they saw shotgun shells and broken glass as they approached the Nortons' mobile home, Mendeke said.

Not knowing whether there were multiple gunmen or whether the gunman was dead, authorities surrounded the homes and began evacuating people nearby.

Mendeke said he called in about 50 to 60 officers from different agencies as well as a Texas Department of Public Safety SWAT team out of caution.
