STRATHAM, N.H. (AP) New Hampshire authorities say a woman who was killed at the company headquarters of Timberland in Stratham was stabbed.

The attorney general’s office also identified the woman as 46-year-old Catherine Heppner, of Exeter. Twenty-year-old Robert Pavao, of Berwick, Maine, was arrested and charged Sunday with two counts of second-degree murder. He’s pleaded not guilty.

Authorities said Pavao was a security guard at the business headquarters and had worked there for four months. They said he had no relationship to Heppner.
