Eugene Victor Britt was born on November 4, 1957, in Gary, Indiana. He grew up in a large family that faced many financial struggles. Both of his parents were alcoholics. His father often abused his mother, creating a difficult home environment. Because of this abuse, Eugene left school at the age of 14. He ran away from home and began living on the streets. During this time, he started using drugs and showed signs of an intellectual disability.

In April 1978, Eugene attacked a 17-year-old girl who was on her way home from Roosevelt High School. He robbed and raped her, which led to his arrest. The court sentenced him to 30 years in prison in December of that year. After serving around half of his sentence, he was paroled in August 1993. Eugene returned to Gary, Indiana, where he had to sleep in homeless shelters because he had no money. During this time, he lived with one of his sisters and took on various low-skilled jobs. In his free time, he rode his bicycle around the city.

In early autumn 1995, Eugene was involved in an accident where he was hit by a train. This caused him serious injuries, and for several weeks, he needed to use a wheelchair to move around.

Eugene Victor Britt was arrested on November 3, 1995, under suspicion of killing 8-year-old Sarah Lynn Paulsen. Her body had been discovered on August 22, 1995, near her home in Portage, Indiana. During the investigation of her death, police found fibers from blue polyester yarns and green colors that matched the uniforms worn by employees of Hardee's, where Britt had worked. He had been seen riding his bicycle near the crime scene. Authorities confiscated his uniform for examination.

Just three days after his arrest, Britt confessed to the murder of Sarah Paulsen and claimed he had killed nine other victims. He told Clyde Smith, the head of the homeless shelter where he had lived, about the murders. Smith persuaded him to turn himself in to the police. After an extensive eight-hour interrogation, Britt admitted to committing ten murders between May 9 and September 12, 1995, and showed officers where he dumped the bodies on a map. Investigators were surprised to find that some victims had been labeled as non-homicidal in earlier reports.

Most of Britt's victims were young girls and women, with one male among the victims. During questioning, he described how he attacked his victims in secluded areas and admitted to raping and strangling them. He also detailed the killing of the one male victim, which was linked to a robbery attempt against him. In this case, he claimed that he was seeking revenge after the attempt on his bicycle.

Police were able to locate bones and clothing based on Britt’s confessions. One of the identified victims was Tonya Dunlap, who was discovered in December 1995. Over time, investigators confirmed the identities of seven victims, despite his claims of ten.

Britt faced trial for the murder of Sarah Paulsen and, in May 1996, he agreed to a plea bargain that spared him the death penalty. He received a life sentence plus 100 additional years. Following this, further investigations led to charges for six more murders and the rape of a 13-year-old girl.

In 2000, defense attorneys argued that Britt was criminally insane, but psychiatric evaluations proved he was sane and fit to stand trial. After delays, he pleaded guilty on October 6, 2006, to several murders, including those of Nakita Moore, Tonya Dunlap, and others, and received an additional 245 years in prison.

Britt was transferred to Indiana State Prison, where he remains as of January 2021, still serving his lengthy sentence.
