On the morning of November 12, 1997, four Union Texas Petroleum (UTP) employees were on their way to work in Karachi, Pakistan. As their station wagon crossed a bridge, two gunmen jumped out of a red Honda Civic and fired into the car. All four American employees, as well as their Pakistani driver, were killed in the attack.
Many observers view the attack as a retaliation against the conviction of Mir Aimal Kansi just two days earlier, though this theory has never been officially confirmed. Kansi was convicted for the 1993 murder of two CIA employees outside agency headquarters in Langley, Virginia.
The Rewards for Justice program is offering a reward of up to $5 million for information that brings to justice those responsible for this attack.
