Robert William Fisher

The backdoor pilot of the CBS show FBI: Most Wanted depicted a story nearly identical to Fisher's. It aired on April 2, 2019, as episode 18 of season 1 of the CBS show FBI. It was written by Rene Balcer, and the series, like its parent show, is produced by Dick Wolf.

In April 2016, FBI officials and Scottsdale police displayed new age-enhanced photos of Fisher during a news conference on the fifteenth anniversary of the murders.

In February 2004, an individual with a striking physical resemblance to Fisher was arrested in Vancouver, British Columbia, Canada by the Royal Canadian Mounted Police. Fingerprints eventually confirmed that he was not Fisher. He was held by Canadian police for approximately one week until a family member correctly identified him. The FBI alerted local law enforcement in 2012 that Fisher may be living in the Payson area in Gila County, Arizona. In October 2014, police raided a house in Commerce City, Colorado after receiving a tip that Fisher was hiding there. Despite arresting two occupants, they did not find any sign of Fisher.

On July 19, a state arrest warrant was issued in Phoenix, charging Fisher with three counts of first-degree murder and one count of arson. Subsequently, he was declared a fugitive, and a federal arrest warrant was issued by the United States District Court for the District of Arizona, charging him with unlawful flight to avoid prosecution. On June 29, 2002, Fisher was named by the FBI as the 475th fugitive to be placed on the Ten Most Wanted list. He was also on the America's Most Wanted "Dirty Dozen" list of the show's most notorious fugitives, and was profiled on The Hunt with John Walsh. The FBI offers a reward of up to $100,000 for information leading to his capture. As of April 2003, FBI had received "hundreds and hundreds of leads." However, all reported sightings of Fisher have been inconclusive or false.

On the morning of April 10, 2001, Mary was shot in the back of the head and her children's throats were slashed from ear to ear in the hours before their house exploded at 8:42 am. Firefighters were immediately alerted to the explosion, which was strong enough to collapse the front brick wall and rattle the frames of neighboring houses for one-half mile (800 m) in all directions. Firefighters kept the 20-foot-high (6 m) blaze from spreading to other homes. A series of smaller secondary explosions, believed to be caused by either rifle ammunition or paint cans, forced them to keep their distance. One suffered minor injuries to his leg when he lost his balance and fell near the burning house.

Fisher, who disappeared at the time of the murders, was named as an official (and to date, only) person of interest in the case on April 14, 2001, when Arizona Department of Public Safety officers were instructed in a statewide bulletin to arrest him. On April 20, the last physical evidence of Fisher's whereabouts surfaced, when police found Mary's Toyota 4Runner and their dog, Blue, in Tonto National Forest, near the town of Young, Arizona, a hundred miles north of Scottsdale. Although police searched the area around where the car was found, it has been alleged that they did not search the nearby network of caves sufficiently. Several professional cavers have suggested that Fisher used these as a hiding place, before either escaping, killing himself or dying from low oxygen levels.

Fisher had been an active member of the Scottsdale Baptist Church's men's ministry, but unlike Mary, he had begun to withdraw from its activities a few months prior to the murders. In 1998, the Fishers went to their church's senior pastor for marital counseling. Fisher told coworkers about a one-night affair with a prostitute he met in a massage parlor. He fretted that Mary would find out that it was the cause of a urinary tract infection that left him ill for several days in December 2000.

Fisher, a U.S. Navy veteran, married Mary Cooper in 1987. He has worked as a surgical catheter technician, respiratory therapist, and firefighter, and is an avid outdoorsman, hunter, and fisherman. Fisher was described as a cruel and distant control freak of a father who was awkward with his children, but who tried to hold on to an image as a devoted family man. His mother-in-law, Ginny Cooper, told investigators that, "Fisher didn't socialize often with family because of a fear of getting too close to people and losing them."

Robert William Fisher (born April 13, 1961) is an American fugitive wanted for allegedly killing his wife and two children, and blowing up the house in which they lived in Scottsdale, Arizona on April 10, 2001. He was named by the FBI as the 475th fugitive to be placed on the list of FBI Ten Most Wanted Fugitives on June 29, 2002.

Robert William Fisher was born in Brooklyn, New York, in 1961 to William Fisher, a banker, and Jan Howell. He has two sisters with whom he attended Sahuaro High School in Tucson, Arizona. His parents divorced in 1976, when Fisher was 15 years of age. According to friends and relatives, the divorce was very turbulent and unsettling, leaving long-lasting effects on him. He reportedly spoke of it with coworkers at Mayo Clinic Hospital and once confided to an associate that his life would have been different had his mother not left the family.
