Narrative:

We were cleared to cross the gep VOR to maintain 11000 ft. I mistakenly descended through 11000 ft to approximately 10500-10400 ft, I then immediately disconnected the autoplt and quickly returned to 11000 ft. The msp approach controller then cleared us to maintain 8000 ft. The controller did not question our altitude deviation. Contributing factors: 1) I'm sure that the captain (PNF) did not make the standard 2000 ft and 1000 ft altitude calls prior to 11000 ft. 2) the night before this, our first leg at approximately XA30 local time, I received a phone call from my wife informing me that my grandma was found dead in her apartment that evening near her birthday. That evening I was unable to sleep at all. Her husband (my grandpa) passed away 4 months earlier. I thought that I could put this event aside, but perhaps I was wrong.
