Timothy John Boham was born on May 27, 1981. He grew up in Colorado. Timothy had a normal childhood and attended school like many other children. As he got older, he began exploring his identity and interests more deeply.

In November 2002, Timothy became known in the gay community when he appeared on the cover of Freshmen magazine, which targets gay men aged 18 to 25. In the following year, he won the title of "Freshman of the Year" in the magazine's annual survey. This exposure opened doors for him in the adult film industry.

Timothy started performing in adult movies under the name "Marcus Allen" in 2004. He worked with Falcon Entertainment and appeared in several adult films. He was featured on magazine covers as well. These opportunities brought him some fame and recognition.

However, Timothy's life took a downward turn. He stepped away from adult films about a year before his crime. He moved to Denver and tried to find a job. He began working for John Paul "J P" Kelso, a businessman, but he only stayed there for about ten days before he stopped showing up for work. Coworkers described Timothy as bright but noted that he seemed distracted.

Timothy John Boham was involved in the murder of John Paul "J.P." Kelso on November 13, 2006. Kelso was found dead in his bathtub by a housekeeper. He was shot at his home in Congress Park, a neighborhood in Denver, Colorado. The police quickly named Boham as a suspect in the murder case.

Boham was arrested three days later on November 16, 2006, at the Mexico-U.S. border in Lukeville, Arizona. Interestingly, Boham identified himself to Customs and Border officers as the person wanted under a murder warrant. After his arrest, Boham was extradited to Colorado, where he was held without bond.

During a preliminary hearing, a detective testified about a conversation he had with Boham while they were in jail. Boham shared that Kelso had asked him to cuddle in the master bedroom. Boham claimed he needed money for his girlfriend and had a different intention when he went to Kelso’s home. He tried to open a safe in the house but found it empty. Boham told family members that he believed Kelso had a lot of money stored in the safe. Court documents revealed that Boham had a history of bipolar disorder and had experienced fits of rage. Boham expressed plans to use any money found for a trip to South America with his girlfriend.

Boham's account of the murder suggested that things escalated when Kelso refused to open the safe for him. This led to a struggle, during which Boham claimed he accidentally shot Kelso. Before leaving for Arizona, Boham returned to Kelso's home multiple times to try to clean up the scene and eliminate any evidence.

The trial for the murder began on June 1, 2009. Boham was found guilty on June 9, 2009. The judge sentenced him to life in prison without the possibility of parole. After the trial, Boham identified as female and is currently serving her sentence in a women’s correctional facility in Denver.
