Raymond McLeod, who was on the US Marshals Service’s 15 Most Wanted Fugitives list for more than six years, has also been assigned a public defender and will be held without bond. His next hearing is scheduled for Jan. 26, 2023. After the hearing, San Diego County District Attorney Summer Stephan told a news conference that McLeod could face 25 years to life if is found guilty of the death of Krystal Mitchell. McLeod was arrested inside his classroom at the El Salvador Raymond McLeod Hearing. McLeod was arrested by agents of the National Civil Police of El Salvador this Monday in Sonsonate, a city located about 63 km west of San Salvador, according to a statement from the US Marshals Service. Joe O’Callaghan, agent of the US Marshals Service, said this Friday at a press conference that the former Marine was arrested in a school classroom while teaching English under another name. Upon being taken into custody, McLeod confirmed his identity and did not object to the arrest, the Service had reported in his statement. Mitchell was found dead in a San Diego apartment in June 2016. Investigators said at the time they found “signs of a struggle” at the crime scene. San Diego Police determined the victim was last seen alive with McLeod.
