The chilling true story of romantic obsession and murder by cancer from the New York Times-bestselling author of The Search for the Green River Killer.

Omaha, Nebraska, 1978. Sandy Johnson was in shock. Her husband, Duane, and young daughter, Sherrie, were violently ill when word arrived that her infant nephew just died of mysterious causes. Days earlier, the entire family was happy, healthy, and living the American dream. Now they were at the center of a terrifying medical crisis.

Duane soon died in a condition unlike anything the doctors had ever seen. As they raced to discover what disease or toxin could have done so much damage so quickly, Lt. Foster Burchard of the Omaha police began to suspect foul play. Sandy herself became a primary suspect, as did her ex-boyfriend Steven Harper-a man prone to violence who never got over their breakup.

In Toxic Love, investigative reporter and true crime author Tomas Guillen offers a detailed and vivid account of this baffling case from the day of the poisoning to the harrowing trial and the murderer's eventual suicide on death row.
