A 25-year-old District man pleaded guilty in court Wednesday to stabbing Delando King to death in August 2010.

According to police, Marcus McLean met the victim at a local gay bar in downtown Washington before accompanying him to his residence in the 1100 block of 10th Street NW around 3 a.m.

When inside the apartment, McLean armed himself with a butcher knife and began stabbing King to death. King was stabbed 28 times, including several times through the heart, a press release from the U.S. Attorney’s Office detailed.

After the stabbing, McLean grabbed a bottle of bleach and poured it over the victim and attempted to clean the crime scene, police said. Before leaving King’s apartment, McLean took his valuables, including a laptop, an iPod and his wallet. Police said credit card records indicate that McLean used King’s credit card to purchase snacks from CVS within an hour after the killing. He continued to use the card to purchase movie tickets, clothes and food in the District and Maryland in the 36 hours before King’s body was found.

In court Wednesday, McLean pleaded to being sane at the time of the killing and admitted that he acted willfully, intentionally and voluntarily when he stabbed King. Originally, he said he had acted in self-defense and he had mental health issues that were unfounded by the court.

The case was scheduled to go to trial April 24. McLean will be sentenced to no less than 24 years.

King, 34, a member of the Navajo Nation originally from New Mexico, worked for the U.S. Indian Health Service at the time of his death.
