"Our decision to conclude the litigation was based solely on the fact that, with the recent assistance of a third party, we are now able to unlock that iPhone without compromising any information on the phone," prosecutors said in a statement.
"We sought an order compelling Apple to help unlock the phone to fulfill a solemn commitment to the victims of the San Bernardino shooting – that we will not rest until we have fully pursued every investigative lead related to the vicious attack," the statement said. "Although this step in the investigation is now complete, we will continue to explore every lead, and seek any appropriate legal process, to ensure our investigation collects all of the evidence related to this terrorist attack. The San Bernardino victims deserve nothing less."
