Michael Oliver Otten, 52, was shot and killed on January 16, 2015, in the 400 block of Linda Drive in San Antonio, Texas. Born September 27, 1962, in Bremen, Germany, Otten was described as a longtime FBI informant tied to a courthouse corruption probe in Bexar County. He was one of two people shot; the other victim was Anthony Reams.

A neighbor across the street, Frank Campos, 44, was arrested the day after the shooting and charged in connection with the killings. The shooting occurred in Otten’s garage and Campos left the scene in Otten’s Toyota Tacoma. Authorities said the deaths were not believed to be related to the federal corruption probe but stemmed from a dispute between neighbors.

Otten is remembered by family and friends as a husband, father, and grandfather. Does anyone have information about the dispute between the neighbors or those who saw activity on Linda Drive that night?
