Killer may have bought on eBay

Ammunition clips purchased on site

BLACKSBURG, Va. -- An eBay account that investigators believe may have belonged to the Virginia Tech killer was used to buy two ammunition clips for the type of gun used in the rampage, according to the auction site.

The eBay account holder with the handle Blazers5505 also sold several books with violent themes and tickets to Virginia Tech football games and lists Blacksburg as his address.

A search warrant affidavit filed Friday stated that investigators wanted to search Seung-Hui Cho's e-mail accounts, including the address

The account holder recently bought two 10-round magazines for the Walther P22, one of the weapons used in the massacre. The clips were bought from a gun shop in Idaho.

He also sold a graphics calculator that contained several games, and bought many books about violence, death, and mayhem.

"The calculator was used for less than one semester then I dropped the class," he said.

His eBay rating was superb -- 98.5 percent. Only one person gave him a negative rating. The site says the person has had an account since January 2004.

Virginia State Police spokeswoman Corinne Geller said investigators are "aware of the eBay activity that mirrors" the Hotmail account. "If that is in fact Cho's account, I don't know."

Meanwhile, investigators pressed ahead yesterday with their search for Cho's motives, even as more of his victims' families said goodbye to their loved ones.

Authorities sought Cho's cellphone records on the chance he warned someone about what would become the nation's worst mass shooting in modern history. They also hope to glean any relevant information from his e-mail and that of Emily Hilscher, one of the first two victims.

"Seung-Hui Cho is known to have communicated by cellular telephone and may have communicated with others concerning his plans to carry out attacks on students and faculty at Virginia Tech," police wrote Friday in an affidavit seeking records from Verizon Wireless. Another possible clue: his phone calls home to his parents. The affidavit says Cho made frequent Sunday night calls home.

Police also sought warrants for Virginia Tech e-mail records in seeking a connection between Cho and Hilscher, who was killed at West Ambler Johnston Hall.
