Oscar Hangstrom, also known as Harold McLellan, is a character in L.A. Noire. He is a person of interest in the DLC case, "Nicholson Electroplating".



Oscar Hangstrom was born in Nevada, Missouri. Hangstrom was a brilliant chemist who worked for the Nicholson Electroplating Plant, and proposed a new process to chemically polish aluminum, which traditionally was done by hand and was usually very labor intensive. The new process was considered revolutionary in electroplating, and worth millions with great value and application to aircraft manufacturing and maintenance. As a result, there were several competitive bids for the process such as Hughes Aircraft and Lockheed. While working for Nicholson, Hangstrom went by the alias of "Harold McLellan", and worked towards personally selling his process to Hughes Aircraft through Vernon Mapes, while cutting out Nicholson.

Events of L.A. Noire

However, the process was actually very unstable. It was unsuitable for electroplating due to explosive reactions to linseed oil, although Hangstrom didn't realize this until too late. While testing the new process at Nicholson Electroplating, a massive explosion occurred and Hangstrom was killed in the blast. Detectives Cole Phelps and Herschel Biggs later arrived at the scene of the explosion.
