CHRISTIANSBURG, Va. (CBSDC/AP) – The man responsible for a shooting at the New River Valley Mall may have broadcast his intentions on a 4Chan message board just before his attack.

According to Gawker, the person identified himself as Neil MacInnis, and described the details of the attack mere minutes before the shooting occurred.

“… I go to New River Community College in Christiansburg, Virgina, 10 minutes away from Virginia Tech,” the post, reportedly published at 1:52 p.m. and obtained by Gawker read. “I’m gonna give y’all the details because the news never gets it right.”

Christiansburg city spokeswoman Becky Wilbur said emergency officials received a 911 call around 2 p.m. about someone with a gun at the college’s satellite location in the mall outside of Blacksburg, home to Virginia Tech. The caller reported hearing shots fired.

The poster goes on to say that he will have a Stevens 320 shotgun, as well as buck shots and slugs, and includes a link to what he claims is his ePortfolio.

The poster added, “I’m a bit nervous because I’ve never really handled a shotgun but a few times with the Christiansburg police.”

The man shot two women at a mall branch of a community college in Virginia Friday before he was subdued by police, a city official said.

One of the victims was airlifted to a hospital and the other was taken by ambulance for treatment, Wilbur said. Their conditions and identities were not immediately available.

The name of the gunman was not immediately released.
