The San Diego County Sheriff's Department has announced a second arrest in connection with the disappearance of Brittany Killgore.
San Diego County sheriff's say a body was found at 2:30 p.m. in an area near Lake Skinner, in Riverside County. The identity of the body found has not been revealed and sheriff's officials did not confirm the body is Killgore.
Killgore, of Fallbrook, has not been seen since last Friday and investigators believe she was a victim of foul play.
According to San Diego County sheriff's officials, 27-year-old Jessica Lynn Lopez was taken into custody at a motel on Rosecrans Street in San Diego and was expected to be booked on suspicion of murder.
While it is unknown what led investigators to Lopez's motel room, 10News has learned that when authorities arrived, they found Lopez with multiple cuts and an apparent suicide note that indicated what happened to Killgore and where her body was.
Investigators believe that Killgore, who lived in Fallbrook and whose estranged husband, Cory, is a Camp Pendleton Marine deployed in Afghanistan, was with 45-year-old Louis Ray Perez, also a Camp Pendleton Marine, just before she went missing, sheriff's homicide Lt. Larry Nesbit said.
"Based on our investigation to this point, we believe there is a strong likelihood Brittany is the victim of foul play,'' Nesbit said.
On Monday, the Sheriff's Department deployed its search-and-rescue units to assist in locating Brittany. Search efforts are centered on the area of De Luz Canyon, north of Fallbrook, the lieutenant said.
On Sunday, detectives arrested Perez on suspicion of possessing a stolen AR-15 military assault rifle. Nesbit described Perez, who was being held at San Diego Central Jail in lieu of $500,000 bail, as "uncooperative and not completely forthcoming about his knowledge, we believe.''
The lieutenant would not comment on the nature of the missing woman's relationship with Perez.
Killgore, a 5-foot-7-inch, roughly 130-pound brunette with brown eyes, was wearing a dark-purple evening gown with shiny floral patterns at the time of her disappearance.
Among the suspicious circumstances in the case was the fact that her cell phone was found by trolley security guards in the Gaslamp District of downtown San Diego even though investigators do not believe she went there on the night she vanished, Nesbit said.
Killgore filed for divorce last week, according to court records.
