A lawyer for a Missouri mother says a pawn shop was wrong to sell her mentally ill daughter a gun that was used in a fatal shooting.
Attorney Jonathan Lowy of the Brady Center to Prevent Gun Violence told Supreme Court judges Wednesday that Odessa Gun & Pawn was negligent.
Pawn shop lawyer Derek MacKay says state and federal laws protect firearms dealers from such claims. Lowy also challenged the constitutionality of a federal gun commerce law.
Colby Sue Weathers fatally shot her father in 2012 on the same day she bought a gun. She is schizophrenic and later was committed to a state mental institution.
Weathers' mother, Janet Delana of Wellington, had asked the pawn shop not to sell her daughter the gun.
Judges didn't indicate when they'll rule.
