Authorities say a woman who was arrested at a Missouri home where a man shot three police officers had been helping the man deal methamphetamine.

State Highway Patrol Sgt. Brian Hagerty wrote in a probable cause statement that 37-year-old Tammy Widger told a fellow investigator that she helped James Waters deal meth in exchange for him paying her bills.

Widger was taken into custody after authorities say Waters shot three police officers who were mistakenly sent to her Clinton home while responding to a 911 call made from another town. One of the officers was killed and the other two were wounded. Waters also died, but investigators don't know if he shot himself or was shot by police.

Widger was charged Wednesday with possession of methamphetamine with intent to deliver and maintaining a public nuisance. Online court records don't list an attorney for Widger, whose bond is set at $25,000.
