UPDATED: Standoff Ends After Deputy Is Critically Shot

A Burke County sheriff's deputy is in critical condition after being shot in the neck while authorities tried to serve commitment papers on a 60-year-old woman.

After a 12-hour standoff, police arrested Joyce Henson early Wednesday at her mobile home near Morganton. She was taken to a mental hospital for evaluation.

Authorities said Henson shot 31-year-old Deputy Martin Lawing shortly after the standoff began Tuesday night. He was trying to toss a phone through a window.

Lawing was airlifted to Carolinas Medical Center.

Authorities said Henson refused to cooperate when deputies arrived at her house and threatened to shoot anyone who approached the door.

She continued shooting at officers until they shut off her electricity and fired 50 canisters of tear gas into her trailer.
