Rochester, MN (KROC-AM News) - A Rochester woman has pleaded guilty to a first-degree aggravated robbery charge for her role in a drug-related robbery in August.

20-year-old Ashley Heckman and 20-year-old John Lockett were arrested after a Winona man and woman reported they were beaten and robbed after they came to the Parkside Mobile Home Park in southeast Rochester to purchase marijuana through a deal they had arranged via social media. A third man, 22-year-old Batri Ismail, is also accused of being involved in robbing the victims and both Heckman and Lockett said he was the person who pulled out a gun and pointed it at the head of the Winona man. The gun ended up being fired into the floor of the mobile home during a struggle between the victim and the robbers before they fled with his cell phone and cash.

Lockett previously pleaded guilty and was sentenced to a stayed prison term and 10 years probation. Heckman is scheduled to be sentenced on December 17th. Ismail recently entered a not guilty plea to a robbery charge and is scheduled to stand trial in April.
