PORTLAND, Ore. • The mother of the Oregon gunman who killed nine in a college classroom apparently wrote about her love of guns in an online forum, referring to places that attempt to pass firearms legislation as "lame states."

Laurel Harper posted her thoughts on Yahoo! Answers, a site that allows people to ask and answer questions about any topic. The Associated Press didn't speak with Harper about the postings, but in them she offered an email address that is linked to her.

Harper wrote enthusiastically about guns and derided gun-control efforts in "lame states," in a three-year-old posting. She said she kept "two full mags in my Glock case...No one will be 'dropping' by my house uninvited."

She also wrote about autism and medical issues.

Harper's son, 26-year-old Christopher Harper-Mercer, opened fire at Umpqua Community College on Thursday. He killed himself when police arrived.
