NEW YORK ( CNN ) -- The FBI has begun interviewing clients of deceased Garden City , New York , lawyer William Parente as part of an investigation into his financial dealings , according to FBI spokesman James Margolin . Stephanie Parente , 19 , was found dead along with her sister and parents in a Baltimore hotel Monday . Margolin said the investigation was launched at the request of police in Baltimore County , Maryland , where Parente , his wife and their two daughters were found dead in a hotel room earlier this week . `` We 're looking into Parente 's business interests and whether there 's any impropriety there and any crime was committed , '' Margolin said . Baltimore County police say Parente , 59 , killed his family before committing suicide . There have been allegations of financial impropriety in the course of the investigation , said police spokesman Cpl . Mike Hill at a news conference Wednesday . A law enforcement source told CNN a cell phone belonging to Parente was recovered in the hotel room where the bodies were found . In an attempt to locate surviving family members , investigators contacted people in the phone 's directory , and some of those people said they were Parente 's investment clients . The New York attorney general 's office confirmed it received a complaint alleging financial wrongdoing from attorney Bruce Montague of Queens , New York . CNN spoke with Montague 's law partner , Steve Drelich , who said he was speaking on Montague 's behalf because Montague is distraught over the death of Parente , whom he considered a personal friend as well as a financial adviser . Drelich confirmed Montague was a client of Parente 's , and said the two had known each other about six years and that Montague had been investing with Parente for about that long . Drelich said Montague 's estimated losses in investments with Parente total about $ 450,000 . Drelich said recently Montague `` got nervous and asked [ Parente ] for his money back , '' in light of highly publicized scandals involving other investors and financial advisers . Drelich said when Montague kept asking Parente about the money , he was told `` it was in a Canadian bank and [ Parente ] was having trouble getting the money back . '' Montague finally received six checks late last week , Drelich said . `` Four of the six checks bounced . We were told there was no money in the account . ... We were told by the bank that the checks were bouncing , '' Drelich told CNN . Drelich said he does n't know the amounts of the two checks that did clear for Montague . It was not until news broke about the Parente family deaths and apparent murder-suicide investigation that Montague contacted authorities , Drelich said . But Drelich emphasized that Montague was more upset with the deaths than any financial loss . `` You can always make more money , '' Drelich said . `` But Bruce is devastated about the family . He considered [ Parente ] a friend , but he 's especially concerned about the family . '' Drelich said his office received calls from at least five other people who said they invested money with Parente , with callers claiming more than $ 4 million in total investments with Parente . Drelich said his office referred those callers to the state attorney general 's office . Baltimore County police said Parente killed his wife , Betty , 58 , on Sunday , April 19 , using `` blunt force trauma '' and asphyxiation . Police said he killed his daughter Catherine , 11 , around the same time , using the same method . Later that day , his daughter Stephanie , 19 , a Loyola College sophomore , was killed also by blunt force trauma and asphyxiation , according to police . Citing hotel records , police said the room was accessed by its electronic key at around 4 p.m. on Sunday , making it plausible that Stephanie entered the room . Later that evening , police said , Stephanie 's college roommate , worried that she had an exam the next morning and had n't come home , called the room and spoke to William Parente . Parente told the roommate Stephanie would be spending the night . Police believe she was dead at the time . Parente died some time later by cutting himself , police said , but would not elaborate further on his death .
