Shanquella Robinson's Sister Frustrated With Investigation Into Her Death

Shanquella Robinson's sister, Tequilla "Quilla" Long, has voiced her frustration at the ongoing investigation into her sibling's death during a press conference.

Robinson, 25, was found lying unconscious in the living room of a rented villa in San Jose del Carbo, a resort city on the southern trip of Mexico's Baja California peninsula, on October 29.

She had traveled to the country with six university friends. An investigation has been launched by both Mexican authorities and the FBI into her death.

Robinson's family said that the friends told the family that she had died of alcohol poisoning. However, a video went viral on social media showing Robinson being attacked.

The Mexican government's death certificate also contradicted the story of alcohol poisoning, saying she had a broken neck and cracked spine.

Long has repeatedly called for more to be done regarding the investigation and has now demanded justice and a full-scale investigation into the details around her death.

Speaking at a "Justice for Shanquella event" news conference on Wednesday, the family spokesperson highlighted their resilience and determination for justice.

Long, who only spoke briefly during the press conference, was asked what justice would look like for the family.

She replied: "Everybody being arrested and doing time in Mexico.

"Everybody extradited over there and doing their time there. That would be justice for us as of now."

She added: "We can't say anything about it, but they're working on it."

Towards the end of the press conference, she also clarified to a reporter that "nobody has been arrested."

Shanquella Robinson's mother, Salamondra Robinson, has also complained about the efforts being made by the FBI in the investigation into her daughter's death.

Sharing a picture of herself and her daughter on Instagram on December 3, she wrote:" Enough is not being done by the FBI to put the individuals who attacked Shanquella behind bars.

"I'm just trying to wait for somebody to be arrested. The FBI is not telling anything as of right now.

"Shanquella's attackers looked me right in my face and told me there was no fight that happened in Cabo Mexico. I believe they are on the run."

She also shared another picture of her and her daughter the following day, with a caption critical of the FBI.

She wrote: "I believe this all was planned. The people Shanquella went on a trip with have all been friends for over 10 years.

"Authorities have not informed me on any information... but I was told the FBI is now questioning from the Cabo 6."

Newsweek has contacted the U.S. State Department, Shanquella Robinson's family, and the FBI for comment.
