Islamabad , Pakistan ( CNN ) -- The widow and mother-in-law of a man killed by a CIA contractor last year were found dead Monday in Lahore , Pakistan , police said . Zohra , the widow of Faizan Haider , and her mother were shot in a family dispute at their home , said police Inspector Javed Siddiqui . The bodies were sent to a hospital for an autopsy , and authorities were seeking a suspect , he said . Haider was one of two men killed in Lahore in January 2011 by Raymond Davis , an American CIA contractor . The deaths sparked a diplomatic tussle that strained relations between the United States and Pakistan . Davis said he shot the two in self-defense when they attempted to rob him at gunpoint as he drove through a busy Lahore neighborhood , but authorities at the time called the case `` clear-cut murder . '' He was charged with murder and illegal possession of a firearm , but was released after more than $ 2 million in compensation was paid to the victims ' families , according to Pakistani officials . The killings caused outrage in Pakistan , a key U.S. ally in the war against al Qaeda and Taliban militants in neighboring Afghanistan . And it heightened tension between the two nations , with Congress warning Pakistani leaders that billions of dollars in U.S. aid could be jeopardized without Davis ' release . Davis appeared in a Lahore court after the payment was made and was acquitted of the charges in accordance with an Islamic practice known as diyat , or compensation . Diyat , enshrined in Pakistan 's penal code , allows victims to pardon a murderer with or without being paid `` blood money . '' Haider 's widow submitted an affidavit to court stating she had pardoned Davis after the payment . The heirs of Fahim Shamshad , Davis ' other victim , also received payment , Rana Sanaullah , the provincial law minister of Punjab province , said at the time .
