More pieces are emerging about David Coleman Headley, who sits in a federal prison in Chicago, charged by the FBI with planning terrorist attacks overseas.

The Inquirer reports that at age 16, he was known as Daood Gilani, the son of Serrill Headley, the Bryn Mawr-bred owner of the old Khyber Pass.

In 1977, Headley took him out of Pakistan, where he attended a military school, and brought him to Philadelphia.

In 1986, his mother gave him the Khyber Pass, which he "ran into the ground," according to Stephen Simons, who now owns the spot, known simply as The Khyber. Mother and son also ran video stores in town.
