Robert Frederick Carr III (December 22, 1943 – July 6, 2007) was an American serial killer and pedophile who killed three children and one woman in the states of Florida and Connecticut between 1972 and 1976.

"[4][5][6] In late 1972, Carr visited Florida and on November 13, 1972, he picked up 11-year-old friends Todd Payton and Mark Wilson, who were hitchhiking from North Miami Beach.

The inside back doors in the car were disabled and the trunk was filled with food, jars of petroleum jelly, and a shovel.

Upon his release in Connecticut, he would kill his fourth and final victim, 21-year-old Rhonda Holloway, before burying her body in a rural area.

Carr, along with detectives David Simmons, Charles Zatrepalek and deputy medical examiner Ronald Wright, went on a long mission to find the bodies.

[10] He served part of his sentence at a state mental hospital, but was kicked out after it was found he was hoarding wire cutters and pliers.
