Meet Anastazia Cretcher and Alexander Dillman.

Cretcher, 19, and Dillman, 26, were arrested after lifeguards reported seeing them having sex “in front of families and other beach goers” Monday afternoon in Daytona Beach, cops say.   

One lifeguard reported that Cretcher and Dillman had “intercourse for approximately 15 minutes” near his watch tower. The other lifeguard said that he “observed the male erect penis penetration the females’s vagina,” according to an arrest affidavit.

Cretcher and Dillman left the beach after being contacted by one of the lifeguards. The pair was busted after a sheriff’s deputy encountered them at the top of a nearby stairwell “in complete nudity.”

While Cretcher denied having sex on the sand, she reportedly said the pair “left the beach to find somewhere more private.”

Both Cretcher and Dillman were charged with indecent exposure, a misdemeanor, and booked into the Volusia County jail (where they remain behind bars). Dillman was also charged with resisting arrest for allegedly refusing to get in a squad car.

Cretcher is facing an aggravated battery count for an earlier incident Monday during which she allegedly struck a female acquaintance with a metal beach umbrella tube. The victim told cops that Cretcher--who is known as “Molly”--had “acted belligerent and exposed herself to beachgoers all day.”

In May, Cretcher was arrested following a bloody altercation with a male friend at a Daytona Beach resort. The victim told cops that his relationship with Cretcher “has been of a sexual nature as they film adult videos together, however neither party views their relationship as dating.” The man claimed that Cretcher bit him in the groin and punched him in the head. While the bite “caused significant injury to his genitals,” the victim told police that he “did not believe it caused any permanent damage.”

Battery and aggravated assault charges were dropped when prosecutors declined to pursue a case against Cretcher, who recently moved to Florida from her family’s Ohio home.
