Headley has been coming to Goa for almost nine years, but more frequently during the run upto the 26/11 attacks on the Taj and Trident Hotels, in Mumbai.
“Headley is one link that connects all the missing pieces of 26/11. He establishes the complicity of the Pakistan Army and Inter-Services Intelligence (ISI) and also indicts Lashkar-e-Toiba (LeT) supremo Hafiz Muhammad Saeed," according to an India Today report (Feb 11, 2013)
The National Investigative Agency found that he was residing in Goa on a tourist visa and was close to an American couple who had been illegally running a business in Goa. The National Investigation Agency is investigating if the Goa-based US nationals were involved, knowingly or unknowingly, in Headley or his Moroccan companion's reconnaissance missions.
The couple was introduced to Headley by his Moroccan girlfriend Faiza Outalha. In February 2007, during one of his nine trips between Mumbai and Pakistan to meet his LeT and ISI handlers, he met Faiza at a mutual friend's home in Lahore. They were married that month.
Headley hid the marriage from Shazia, whom he married in 1999 and had four children with. In March 2007, he brought Faiza to Mumbai where they extensively recceed the Taj Mahal hotel, which was then the only target of the strike.
Importantly he then brought Faiza to Goa (Source: India Today report, Feb 11, 2013, except the part about the coming to Goa with Faiza which is Herald’s independent information)
