Very realistically made video about the last seconds:
Airrebels.com
It supports my theory:
Came in fast and high, disengaged AT, forgot it there, trim went full aft, pulled shortly before stall, pushed throttle full forward, nose went even higher, speed incresed, stall avoided, high ROD, shortly before impact some flare, controlled landing, crash.
Video created after eyewitnesses, not according ADS-B data.
