-LRB- CNN -RRB- -- Mourners packed into a church in Illinois Monday to remember a woman whose death made headlines worldwide . At the St. Rita of Cascia Shrine Chapel in Chicago , a funeral was held for Dawn Brancheau , a SeaWorld trainer who died last week after a killer whale dragged her underwater at Shamu Stadium in Orlando , Florida . A memorial service for the 40-year-old will take place in Orlando , Florida , at a future date , according to the Blake Lamb Funeral Home . Brancheau had wanted to be an animal trainer from the time she visited SeaWorld as a 9-year-old , her sister Diane Gross said last week . `` It was her dream job , '' Gross said . `` She loved the animals like they were her own children . ... She loved what she did . '' Brancheau was pulled underwater Wednesday at SeaWorld Orlando , when a 6-ton killer whale named Tilikum grabbed her ponytail . A source at SeaWorld said the whale dove deep underwater after seizing Brancheau . Trainers had to wrangle the animal into a smaller pool before they could retrieve her body about 40 minutes later . The same whale was linked previously to two other human deaths . Tilikum and two other whales were involved in the 1991 drowning of a trainer at a marine park in Victoria , British Columbia . The trainer fell into the whale tank at Sealand of the Pacific and was dragged underwater as park visitors watched . In 1999 , Tilikum was blamed for the death of a 27-year-old man whose body was found floating in a tank at SeaWorld , the apparent victim of the whale 's `` horseplay , '' authorities said then . Labor Department spokesman Mike Wald said the safety and health agency is looking into whether Occupational Safety and Health Administration workplace standards were violated in Brancheau 's death . The agency will complete a report within six months , he said . If workplace infractions are found , OSHA will propose financial penalties , Wald said . If that happens , the company could accept the penalties and make needed workplace changes or appeal the penalties before an OSHA review commission . Inspectors also are looking into the incident from an animal-welfare perspective , said David Sacks , an Agriculture Department spokesman . The Animal and Plant Health Inspection Service wants to know whether federal standards were violated in the exhibiting of warm-blooded mammals . SeaWorld shows with killer whales resumed on Saturday .
