The family of a Nicaraguan doctor who was found dead inside a walk-in freezer at a Little Havana Dollar Tree has filed a $50 million wrongful-death lawsuit against the corporation and the store’s manager, alleging negligence and dangerous conditions.

The lawsuit, filed Wednesday on behalf of the estate of Helen Massiell Garay Sanchez, states that the 32-year-old anesthesiologist became trapped inside a walk-in freezer at a Dollar Tree store and died as a result of fatal injuries sustained while inside.

Sanchez’s body was discovered on Dec. 14 by a store employee, according to the complaint. She had entered the store the previous day. Her estate includes her father, her husband, and her two children.

According to the lawsuit, the store breached its duty of care by allowing Sanchez to enter the freezer without warning her of potential dangers and by failing to install basic safety features. The filing alleges the freezer lacked an internal emergency release, latch, or alarm that could have prevented entrapment.

The suit also claims the store failed to properly monitor surveillance footage and did not ensure employees were adequately trained to confirm that all customers had exited the store before closing.

The lawsuit names the store’s manager, Yanelkis Gonzalez, as a central defendant. It alleges that another customer told Gonzalez that Sanchez was missing and asked her to review surveillance footage, but Gonzalez allegedly refused.

Sanchez had been visiting Miami to see family at the time of her death. According to her social media profiles, she was an anesthesiologist specializing in congenital heart disease at Manuel de Jesús Rivera Children’s Hospital in Managua, Nicaragua, and also worked at Dr. Mauricio Abdalah Hospital in Chinandega.

Police were called to the store on the morning of Dec. 14 and opened an investigation. Authorities previously said there was no evidence of foul play and that Sanchez entered the freezer “of her own free will,” according to a spokesperson for the Miami Police Department.

The lawsuit disputes that characterization, arguing that unsafe conditions and a lack of basic safety safeguards directly contributed to Sanchez’s death.

Her autopsy report, including the official cause and manner of death, has not yet been publicly released.
