Third arrest made in murder of Marine wife Brittany Killgore

In a case riddled with loose ends and unanswered questions, a California woman is being held on $3 million bail and has been charged with the murder of a Marine's wife. NBC's Mike Taibbi reports.


Sheriffs have arrested a third suspect in connection to the murder case of Marine wife Brittany Killgore, who was killed last month.

Dorothy Grace Marie Maraglino, 36, a Fallbrook, Calif. resident, was taken into custody at 6:30 p.m. Thursday at a hotel in downtown San Diego, according to sheriffs.

Homicide detectives said Maraglino’s arrest – the third in Killgore’s case – was made as a result of information and evidence obtained throughout the ongoing investigation.

A source inside the sheriff’s department told NBC 7 San Diego that Maraglino has been a “person of interest” since Killgore disappeared last month.

Address searches reveal that Maraglino was living at the same house on East Fallbrook Street where two other suspects -- 45-year-old Marine Louis Perez and 25-year-old Jessica Lynn Lopez -- who have been arrested in Killgore’s murder also lived at one point.

Killgore, 22, went missing on April 13. Her body was found abandoned in Riverside County on April 17.

At a hearing last month, a prosecutor said investigators found Killgore’s blood and a weapon in Perez’s car.

Both Lopez and Perez have pleaded not guilty in the murder of Killgore. Investigators say that three days after seeking a divorce from her husband deployed in Afghanistan, Killgore disappeared after a night out with Perez.

Perez, 45, a Marine for 16 years, is married and has lived in the San Diego area for 10 years.

Killgore cited irreconcilable differences in her divorce filing but gave no other details.

"My wife Brittany, was beautiful beyond words and her murder has left me devastated," Marine Lance Cpl. Cory Killgore said in a statement.

No further information about Maraglino’s alleged involvement in this case has been released.
