During a news conference Nov. 14, Metropolitan Police Chief Peter Newsham announced that, with the help of the Montgomery County Police Department, the Federal Bureau of Investigation, the United States Attorney’s Office and the US Marshals Service, a suspect wanted in connection to several sexual assaults and a murder had been arrested.

Sixty-year-old Giles Daniel Warrick was arrested Nov. 13 and charged with first-degree murder and sexual assault.

According to a press release, Warrick is being charged for the death of 29-year-old Christine Mirzayan, a congressional fellow, in 1998. Mirzayan was finishing a policy fellowship program in DC.

During the evening hours on Aug. 1, Mirzayan was walking in the 3600 block of Canal Road, NW, when the suspect approached her, the release said. The suspect physically and sexually assaulted the victim. On Aug. 2, 1998, the victim was found dead at the listed location.

Nesham said she had been struck several times in the head with a large rock in addition to being raped.

Warrick, who owned a landscaping company and was a utility contractor, is also connected to nine other assaults in the Washington-metropolitan area from 1991-1998. The victims ranged in age from 18 to 41 years old.

Newsham said Warrick’s DNA was a match to all of the attacks.

There is a possibility that other assaults may have occurred. It is believed that Warrick recently relocated to South Carolina from the District.
