Two paintings were stolen from a Brazilian museum, including a Picasso, when thieves broke in Thursday morning. The break in lasted a total of three minutes, but that was enough for the thieves to make off with Picasso's "Portrait of Suzanne Bloch."

Candido Portinari's "O Lavrador de Cafe" was also stolen from the Sao Paulo Museum of Art. Investigators say the thieves appear to be professionals and used a car jack to pry into a metal pull-down gate over the museum's front door. Then, they broke two glass doors and took the paintings from the museum's second floor.

Police have sent alarms out to try and keep the paintings from leaving the country. Surveillance cameras caught images of three men entering the museum, but did not get a clear picture. A fourth person is believed to have been involved. Estimates put the paintings worth nearly $100 million.
