A family is demanding answers days after New York mother who traveled to the Dominican Republic reportedly died moments before undergoing liposuction.

According to the Daily Mail, Johana Gonzalez, 25, died Tuesday while being prepped for the elective surgery at the Center for Plastic Surgery and Liposculpture (El Centro de Cirucia Plastica y and Lipoescultura, CECILIP) in Santo Domingo. A lawyer representing the family said the mother-of-three entered the operation room at 7 a.m. and suffered a heart attack moments later.

The woman’s mother, Yocalis Alvarez, told Univision 41 that she advised against getting liposuction. However, Gonzalez didn’t heed her warning, reportedly traveling to the Dominican Republic on July 24 with her three young children in tow.

“I want to know what caused my daughter’s death, and if it was negligence [then] that doctor can’t continue to kill more young women like he did with my daughter,” she said.

Local media outlets released a recorded conversation that apparently catches Dr. Argeny Mercedes telling relatives that all pre-surgery exams have been completed. The Daily Mail reported that Gonzalez died before an incision was made.

However, the family told Telemundo 47 that they’ve received several different accounts of what led up to Gonzalez’s death. They also accused the doctor of calling them and requesting not to get an autopsy for Gonzalez.

The woman’s husband, Jency Castro, claimed the doctor informed him of his wife’s death several hours afterward. He said he still wants answers but their children just want their mother’s body to come home.
