An overweight lab technician with low self esteem, brought on by his dominant mother, becomes a serial killer of female nurses.

Leo Kroll, a lab technician in a large unnamed city, is responsible for the strangulation murders of several young nurses. He feels that in some twisted way, he is getting back at his overbearing shrew of a mother. Leo also kills the nurse who is taking care of his mother in the rest home she is staying at. As a result, Mrs. Kroll dies from a heart attack. He also kills an arcade worker whom he feels can identify him.—Brian Washington <[email protected]>
