Oregon community college gunman described as ‘timid’, ‘unfriendly’ by various neighbors

A neighbor of the man authorities say killed at least nine people at an Oregon community college Thursday told reporters the gunman “seemed really unfriendly.”

Bronte Harte told the Associated Press she lived in the apartment below 26-year-old Christopher Harper Mercer in Winchester, Ore. Winchester is approximately five miles north of Roseburg, where Mercer opened fire in a classroom at Umpqua Community College, killing nine people before being killed in an exchange of gunfire with responding officers.

Harte said Mercer would often “sit by himself in the dark in the balcony with this little light.” She added that a woman she believed to be Mercer’s mother also lived upstairs and was “crying her eyes out” Thursday.

Harte also told the New York Times Mercer would frequently yell at her for smoking on her apartment’s balcony.
