Sucks to hear this, I've been a long time Peter Falk fan.
Columbo was an awesome show and all the new trendy CSI bullshit type shows could learn a thing or two from Columbo.
One of my favorite Peter Falk quotes talking about how he got into doing artwork as a hobby-
"I opened a door and there she was, a nude model, shoulders back, a light from above, buck-ass naked. The female body is awesome. Believe me, I signed up right away."
