Police in Thailand's capital say they have identified a man whose body parts were found floating in the city's Chao Phraya River as a Spanish consultant, and also have identified suspects in his killing.

Police Gen. Panya Mamen told reporters Thursday that police are gathering more evidence and searching for the suspects, and believe they can solve the case within 48 hours.

Panya said the victim was a Spanish man who had traveled to Thailand a number of times, but only provided his surname, David. He said police were able to match DNA from the seven body parts that were found and that from a man reported missing.

He said the man apparently was forced to turn over money to the suspects, and was then killed to silence him.
