Shankella Robinson’s family filed a lawsuit against friends 2 years after her death

Shankella RobinsonTwo years after her mysterious death in Mexico, the family wants justice.

Shankella, 25, of Charlotte, North Carolina, died on Oct. 29, 2022, while vacationing in Cabo San Luca with six other people, who have since become known as the “Cabo Six.”

Her travel companions allegedly insisted she died of alcohol poisoning, but an autopsy conducted by Mexican authorities revealed that her death was caused by violence — specifically, a “dislocated atlas and cerebellum,” PEOPLE previously reported.

As questions about her death remain unanswered two years later, Shankella’s mother, Sallamondra Robinson, has filed a lawsuit against the Cabo Six, as well as the United States Department of State and the Federal Bureau of Investigation (FBI), including the sources. WBTV, ABC News and The Charlotte Observer.

According to documents released by WBTV, Sallamondra is seeking more than $25,000 in damages from each of the six people Shankella was traveling with at the time. Documents filed in Mecklenburg County Superior Court on Friday, Oct. 25, state that the plaintiff is seeking damages on various grounds, including battery, civil conspiracy and intentional infliction of emotional distress.

Salamondra is also seeking more than $25,000 in damages from the US State Department and the FBI in the suit.

Speaking about the lawsuit in press conferenceSallamondra appeared with her lawyer, Sue-Anne Robinson.

“We need justice for Shankella Robinson,” Shankella’s mother said, urging people to “get involved.”

“Two years have passed and there is no reason why no one has been arrested yet,” she added.

Lawyer Sue-Anne told the conference: “The lack of justice serves as a painful, painful reminder of the vulnerability that people, especially young black women, face when they seek adventure in unfamiliar places with unfamiliar faces,” adding: “It is our responsibility to that such tragedies do not go unanswered.”

When PEOPLE reached out to the FBI for comment, the department shared that it is their “standard practice to decline to comment on pending legal proceedings.”

Sue Ann and the US State Department did not immediately respond to PEOPLE’s request.

The lawsuit was filed after Shankella’s family attorneys, Ben Crump and Sue-Anne, sent a letter to the president Joe Biden asking him to put pressure on the authorities for the purpose of arrest in March 2023.

The following month, the US Department of Justice stated in a news release that based on the available evidence, the authorities “concluded that federal charges cannot be filed.” The release at the time claimed that a separate autopsy had been conducted in the US, but did not elaborate on its findings.

A few weeks after Shankella’s death, a brutal and disturbing video began circulating online showing her being beaten in what appeared to be a luxury villa where she was vacationing when she died.

In November 2022, Mexican authorities labeled her death a femicide, a gender-based homicide and a hate crime, and Mexican law enforcement issued an arrest warrant for one of Shankella’s companions. US authorities have not named the man.

Until talking to PEOPLE Last April, Shankella’s mother, Sallamondra, said she received a call from her daughter hours before her death.

“She said they all had a good time and I told her I’d talk to her tomorrow,” Sallamondra said. “And I never spoke to my daughter again.”
