Deputies say it is likely foul play is involved in the disappearance of 22-year-old Brittany Dawn Killgore, who was last seen Friday.

"We believe there is a strong likelihood Brittany is the victim of foul play," said Sheriff's Lt. Larry Nesbit.  "Today,  we are deploying sheriff's search-and-rescue units to assist in locating Brittany."

Nesbit said Killgore was last seen with a Camp Pendleton Marine, 45-year-old Louis Ray Perez, wearing a dark purple evening gown with floral glitter patterns, authorities said.

According to The Los Angeles Times, Perez was questioned regarding the missing young woman and was uncooperative. Nesbit said that on Sunday, Perez was arrested on suspicion of possessing a stolen weapon, an AR15 assault rifle.

Meanwhile, Killgore's cell phone was found Saturday in San Diego's shopping and entertainment district, the "Gaslamp Quarter."

Court documents state Killgore filed for divorce last week from her husband of two years, who is returning now from Afghanistan because of the disappearance. He is not suspected of being involved.

Perez is now being held on $500,000 bail and set to be arraigned on Wednesday.
