Light Twin over NYC

during the hour or so i was able to spend in my neighborhood today i noticed a white twin prop flying around in strange patterns. it looked like it was heading to LGA, though could have just been transient through the airspace. now that i'm at work staring at my PASSUR screen i see a N110DS flying LGA-RYY. this thing is doing 340 kts, so it's got to be a jet.

so now the question is, what did i see this morning? could that have been a mitsubishi MU-2? the airplane i saw was a twin prop, center mounted wings. anyone here know the type? the one i saw looked a little like a Dornier, 228 but i've yet to see

N110DS is a Mitsubishi MU-300 Diamond...according to a photo on JPnet it is owned by televangelist Pat Robertson.

Govt boys? Homeland Security, Customs or Justice (FBI) dept? I know Justice/FBI do use
fixed wings sometimes around here.
