Los Angeles ? The family of a 17-year-old girl who died hours after her health insurer reversed a decision and said it would pay for a liver transplant plans to sue the company, their attorney said Friday.

Nataline Sarkisyan died Thursday about 6 p.m. at the University of California, Los Angeles Medical Center.

She had been in a vegetative state for weeks, said her mother, Hilda.

Attorney Mark Geragos said he plans to ask the district attorney to press murder or manslaughter charges against Cigna HealthCare in the case. The insurer “maliciously killed her” because it did not want to bear the expense of her transplant and aftercare, Geragos said.
