(CBS/AP) CHICAGO - The widow of Chicago lottery winner Urooj Khan, who authorities say was poisoned with cyanide shortly before he was to collect $425,000 in prize money, has battled with his siblings over control of his estate, court documents show.
Khan, who owned several dry cleaning operations and some real estate, died suddenly on July 20, just days before he was to collect his winnings from the Illinois Lottery. With no signs of trauma, authorities initially ruled he died of natural causes, but a relative came forward with suspicions that prompted a fuller examination that led to the startling conclusion that he was intentionally poisoned.
The probate court documents add a layer of drama to an already baffling case. As they work to unravel the mystery, police, prosecutors and the medical examiner have revealed little. They have named no suspects and declined to say if the lottery win might have presented a motive.
In another development Wednesday, a lawyer for the man's widow, Shabana Ansari, said Chicago police detectives questioned her in November for more than four hours at a police station and executed a search warrant on the two-story home where she lived with Khan.
Attorney Steven Kozicki said Ansari maintains she had nothing to do with the death of her 46-year-old husband and he has no indication that investigators might be looking at her as a potential suspect.
The fact that Khan died without a will opened the door to the legal tussle over his estate, which his wife says amounts to more than $1.2 million, including the prize money, his share of the dry-cleaning businesses and real estate, as well as several vehicles and a bank account.
Under Illinois law, Khan's estate would be split between his wife and 17-year-old daughter from a previous marriage.
However, Khan's brother Imtiaz and sister Meraj Khan expressed concern in court filings that Khan's daughter might not get her fair share. The siblings, who live in the Chicago area, are not staking a claim to any of the money for themselves. They initially won an order from a probate judge in September to freeze the lottery check, asserting his widow tried to cash it.
Meraj Khan is also seeking to become the legal guardian of the teen, who lives with Ansari.
Ultimately, the probate judge granted Ansari's competing request to administer the estate but has yet to decide how to divide the assets, including the lottery payout. The assets remain held up by the court proceedings, and Ansari denies removing any of the assets.
The next status hearing is scheduled for Jan. 24.
