Attorneys Ben Crump and Sue-Ann Robinson have sent a letter to President Joe Biden and Secretary of State Antony Blinken calling for the White House to take action in Robinson's death. 
The attorneys,  on behalf of mother Salamandra  Robinson, encourage the U.S. to extradite Shanquella's killer to Mexico or the U.S. takes jurisdiction of the case.  An FBI investigation is underway.  
Shanquilla Robinson traveled from North Carolina to Cabo San Lucas, Mexico with friends. It is one of those friends who stand accused in Robinson's death. According to a Mexican police report, a doctor was called to assist Robinson around 2 p.m. The doctor insisted on taking her to the hospital, but her friends refused.   
According to Robinson's death certificate, she died from a severe spinal cord injury and a broken neck. Doctors call the injury an internal decapitation. A video surfaced after Robinson death showing her being beaten by one of the traveling friends.
The documents submitted to the White House named the friend and calls for her to be extradited to face charges.
