A vacationer recently returned to his home in Santa Monica to find a thief had made off with more than a dozen works of art by the likes of Piet Mondrian and Jasper Johns, five luxury watches with makers like Patek and Breitling, wine, cash and a red Porsche Carrera.
Police said in a statement Wednesday that the take totals more than $10 million.
The burglar struck between Sept. 12 at 3 p.m. and Sept. 13 at 8:00 p.m.
Police released pictures of the art, and are offering a $1,000 reward for tips leading to arrests.
They gave out no information on possible suspects.
