The case remains difficult for the investigators and it is not clear what charge they will be able to bring.
In a statement late Friday, the US Capitol Police indicated that the coroner’s report on Seknik’s death was not yet complete: “We are awaiting toxicology findings and continue to work with other government agencies regarding the investigation of the death.”
“The officer’s family requested privacy during this difficult time and for the spread of misinformation regarding the cause of his death,” the statement said. “Management and the Sicknick family appreciate the outpouring of support for our fallen officer.”
Investigators struggled for weeks to build a federal homicide case in Sicknick’s death as they pondered videos and photos to try to determine the moment he suffered his fatal injuries. Investigators determined that initial reports that Sicknick had been hit by a fire extinguisher were incorrect, CNN previously reported.
Several people were charged with assaulting police officers in the weeks following the attack, but no one has yet been charged in connection with Sicknick. More than 100 other police officers were injured in the clash last month, including at least 15 who required hospitalization, according to court documents.
