NEW YORK - A key gov­ern­ment wit­ness in the New York in­sid­er trad­ing tri­al of a San Fran­cis­co hedge fund own­er has end­ed her tes­ti­mo­ny af­ter say­ing her life was de­stroyed by her crimes. Roomy Khan fin­ished tes­ti­mo­ny Thurs­day that spanned four days in fed­er­al court. Khan told a ju­ry hear­ing ev­i­dence against Doug Whit­man that she re­grets shar­ing in­side in­for­ma­tion for sev­er­al years be­fore she be­gan co­op­er­at­ing with the gov­ern­ment five years ago. She said her "life has been de­stroyed" through dam­age to her rep­u­ta­tion and mon­ey lost. Khan is co­op­er­at­ing with the gov­ern­ment for a sec­ond time. She plead­ed guilty to wire fraud charges in a co­op­er­a­tion deal in 2001. In the lat­est deal, she ad­mit­ted to in­sid­er trad­ing in what be­came part of the biggest in­sid­er case in his­to­ry.
