Suspects in Marine Wife's Case Linked Through Home Property records show that three suspects in the death of a Marine's wife were linked through a home that has been owned by one and listed as the residence of the others. Dorothy Grace Marie Maraglino, who was arrested late Thursday, owned the yellow stucco home in Fallbrook as of August 2010, records show. Maraglino was arrested at a hotel in downtown San Diego and booked on suspicion of murder in the death of 22-year-old Brittany Killgore, San Diego County Sheriff Bill Gore said. Maraglino, 36, was scheduled to be arraigned Tuesday in Vista. Sheriff's records contained no indication that she had a lawyer. Tanya Sierra, a spokeswoman for the San Diego County district attorney's office, said Friday that no decision had been made on whether to file charges against Maraglino. Louis Ray Perez, 45, a Marine staff sergeant, and Jessica Lynn Lopez, 27, have pleaded not guilty to the murder. Prosecutors have said the two lived together at one time but have not said when or where. Maraglino has had a registered business named Rwayom Minote since July 2008. State records do not describe the nature of the San Diego company. Authorities have not indicated a motive for the slaying. Gore said late Thursday that Maraglino's arrest was the result of evidence obtained during the investigation. A sheriff's department spokeswoman, Melissa Aquino, declined to comment on the case Friday. The house is a mile from Killgore's apartment in Fallbrook, a town of 38,000 people known for its avocado orchards and proximity to Camp Pendleton. Killgore was last seen April 13 in a purple evening gown, three days after she filed for divorce from Lance Cpl. Cory Killgore, who was serving in Afghanistan at the time. Prosecutors say Killgore met Perez for a night out but things quickly went wrong. "She sent a text saying, 'Help,'" Patrick Espinoza, a San Diego County deputy district attorney, said at Perez's arraignment last month. She was missing from that point on. Investigators found Killgore's blood and a weapon in Perez's car, according to prosecutors. Perez told investigators he dropped off Killgore in downtown San Diego's bustling Gaslamp District, but investigators concluded that he lied about his whereabouts and stayed about 60 miles north in Fallbrook. Cory Killgore has not been named as a suspect or person of interest in the killing and has said he is devastated by his wife's death. The couple married in July 2010.
