A Vancouver teen is suspected of shooting a Beaverton man she targeted on a dating website where "sugar daddies" lavish young love interests with cash and other gifts in exchange for companionship, according to Washington County authorities.

Raelyn Domingo, 15, faces first-degree assault and robbery charges after investigators say she arrived at Thomas Licata's suburban home last week, got high with her host and then fired a single bullet into his belly.

"From what we know, she shot him unprovoked," said Deputy Jeff Talbot, a Washington County Sheriff's Office spokesman.

Both charges are Measure 11 crimes.

Licata, a married 56-year-old, said he recently met the teen on the Seeking Arrangement website, which boasts its "Sugar Babies and Sugar Daddies ... both get what they want, when they want it," according to a probable cause affidavit.

Domingo, who attended Heritage High School in Vancouver, appeared on the site under the profile name "asianperssuasion" and claimed she was a certified nursing assistant, court records show.

Per Licata's suggestion, the two met Friday at the Safeway on Murray Boulevard, and he drove them to his 4,000-square-foot home in the 8600 block of Muledeer Drive, records show.

The pair retreated to Licata's music room, where he paid Domingo $260 and gave her seltzer to drink, he told investigators. The two then hit his vape pen, and the girl left to use the bathroom.

Domingo returned a few minutes later, whipped out a gun and shot him in the stomach, Licata told authorities. She demanded more money from the wounded man, who works as a consultant and investment banker, but he had no more cash.

She left the home. Licata was later rushed to OHSU hospital, according to the affidavit.

Hours later, police say, Domingo and three masked men robbed a pair of Camas residents at gunpoint in their home, prompting a separate investigation in Washington state.

Authorities, including members of the U.S. Marshals Service Fugitive Task Force, arrested Domingo in Vancouver on Wednesday.

She's being held at the Clark County Juvenile Justice Center. Domingo faces a first-degree robbery charge in Camas, police said.

Oregon authorities plan to extradite the teen from Washington state.
