The lack of forward speed suggests sinking air
Sinking air will give you a negative vertical speed but it won't kill your forward speed.
Pulling back on the yoke (to maintain altitude) will reduce the forward speed but only to the point of stall.
It will be quite difficult to reduce forward speed much below Vs.
And of course you will have the stall warner and the whole orchestra going off so only somebody deaf and blind will carry on doing that.
