A Bar Nunn woman who initially pleaded not guilty by reason of mental illness or deficiency has admitted to her role in the burglary of a home and the assault of two residents in their seventies back in February.

Sharon Marie Hinkle, 45, pleaded guilty Friday in Natrona County District Court to one count of conspiracy to commit aggravated burglary and one count of conspiracy to commit aggravated assault.

The charges carry a combined maximum sentence of 30 years in prison. Under a plea agreement, prosecutors have agreed to recommend Hinkle serve no more than seven to 10 years in the Wyoming Women's Center on each count, with those sentences running concurrently.

Hinkle also agreed to testify against her alleged co-conspirator, 43-year-old William Mason Quillen, who is charged with two counts of aggravated assault and one count of aggravated burglary. He could face five to 45 years in prison if convicted on all counts.

Court documents say Hinkle was dating Quillen when, on the night of Feb. 8, the pair kicked in their neighbors' door in the 4800 block of Bel Vista Drive and demanded they be given a safe.

The neighbors, a 71-year-old man and a 70-year-old woman, said they didn't have a safe. Quillin allegedly attacked them.

According to affidavits, the man was able to get away and went to a neighbor's house for help. Quillin reportedly followed him.

Somewhere near the neighbor's house, Quillin allegedly picked up a snow shovel and bear the man with it. The victim reportedly suffered severe injuries.

The neighbor reportedly saw what was going on and had someone call 911. Quillin left the area.

Both victims were taken to Wyoming Medical Center.

Natrona County Sheriff's deputies found Quillin and Hinkle at Hinkle's home in the 4000 block of Bel Vista Drive late Wednesday. They tried to contact the couple, but got no response.

The Special Response Team was called out and a standoff ensued. Officers spent over nine hours using a loudspeaker to ask Quillin and Hinkle to surrender themselves.

Tear gas and non-lethal rounds were used to subdue the pair. Officers entered the home and arrested both Quillin and Hinkle shortly after 9 a.m. Thursday, Feb. 9.

Quillin, who will also undergo a mental evaluation, is charged with one count of aggravated robbery and two counts of aggravated assault. He is being held on a bond of $1.5 million and could face five to 45 years in prison if convicted.

Hinkle is currently free on bond.

Quillen remains in custody on a bond of $1.5 million.
