There is a detailed article about this observation in the journal Avifaunistik in Bayern in German
with an abstract of the article in English
An unusual heron was discovered by Alexander Wöber on 27.06.2004 at the Neusee near Mönchstockheim, Lkr. Schweinfurt in northern Bavaria, southern Germany.
Photos could be taken only from the upper parts of the bird, but the brownish breast and belly could be seen by all watchers present (R. Jahn, H. & H. Schaller, D. Uhlich, A. Wöber). Additionally the wings with white spots at the front were well shown while the bird took off. Since then the bird couldn't be seen again.

A Hybrid Grey Heron x Purple Heron Ardea cinerea x Ardea purpurea
The slender bill and the dark stripe from the neck leading under the eye to the bill speak for Purple Heron. But white parts of the head, grey parts of the neck and the white spots at the wing can hardly be explained by an color aberration of Purple Heron. These characteristics along with some structures like the strong neck fits well with Grey Heron. So the most probable explanation for this strange bird is a Grey x Purple Heron-Hybrid.
There are only few publications about that kind of hybrid (information from www.bird-hybrids.com ):
