The Miami-Dade State Attorney's office announced Thursday that prosecutors will not bring charges against Kaepernick, 49ers wide receiver Quinton Patton and Seattle Seahawks receiver Ricardo Lockette, who were all named in an incident report filed April 4.
"The case was not dropped. There was never a case. It was an investigation," Miami-Dade PIO Ed Griffith told NFL Media Insider Ian Rapoport. "The essence is, there was no indication of a sexual assault, so nothing was filed."
Last month police released two 911 calls in connection with the case in which the two separate callers spoke of a woman who would not leave a hotel room where the three players were said to be.
Kaepernick said the April incident changed his "way of thinking."
