According to the chargesheet, accused Parveez Tak killed Laila and members of her family, because three of the deceased refused to share their earnings with him.
"In 2010, Laila's sisters Azmina, Zara and Reshma went to work in Dubai with one Sheikh who was known to Tak", the chargesheet said.
"When they returned, they refused to share their earnings. Tak had a grudge against them and he conspired to kill them to usurp their property," the chargesheet said.
Earlier, the crime branch had said that Laila's mother Celina was married to Asif Sheikh (her first two husbands were Nadir Patel and Tak), though she told Tak that Asif was her brother. However, Tak always suspected that Celina and Asif had an affair.
The crime branch had also said that Tak did not like Asif still maintaining contact with the family and "the family's decision to relocate to Dubai also made him feel abandoned, as he did not have a passport".
The 1000-page chargesheet filed against Tak on October 3 however mentioned, that the only reason attributed to the killing of Laila and her family members is her sisters' refusal to share their earnings with him.
Tak has been accused of killing Laila (30), her mother Celina (51), her elder sister Azmina (32), twin siblings Zara and Imran (25)and cousin Reshma. The family had gone missing in February 2011 from Mumbai.
