OKLAHOMA CITY (AP) - A mother from Lawton whose 19-year-old university student son was shot and killed in Oklahoma City in 2009 is among those urging state lawmakers to defeat a bill that would allow people to carry guns in public with no training or background checks.

Kari Wahnee was at the state Capitol on Wednesday with members of the Oklahoma chapter of Moms Demand Action for Gun Sense in America. The group is among a diverse group of businesses and institutions opposed to two separate gun bills pending in the Legislature.

One dubbed "constitutional carry" would allow most adults to openly carry loaded handguns in public without any license, background check or training.

A separate measure calls for a public vote on further loosening state gun laws.
