(CNN) – The House Oversight Committee is launching an investigation into at least 10 deaths and disappearances.

The cases involve people connected to nuclear and aerospace research at organizations such as the Air Force, NASA and Los Alamos National Laboratory.

The incidents have happened over the past three years.

The House committee wants the FBI, the Defense Department, the Department of Energy and NASA to provide briefings.

Families of two of the people have said medical conditions or personal struggles explain what happened to them.

There are no known links between the cases.
