ORANJESTAD, Aruba (AP) – A fourth man detained in the case of a missing US teen is a disc jockey aboard a tourist boat offering nightly party cruises, his employer said yesterday.

Steve Gregory Croes, whom authorities earlier identified only by his initials, “SGC,” said he was contacted by police Thursday night and went to the station voluntarily to give a statement, according to the employer, Marcus Wiggins. Croes was arrested early yesterday.

Croes also said he knew one of two Surinamese brothers being detained in the case because he went to the same Internet cafe, Wiggins told The Associated Press.

Croes was working as a disc jockey on the “Tattoo”, a large tourist boat offering nightly dining, dancing and swimming, Wiggins said.

Wiggins said he had seen neither the Surinamese brothers,

Deepak Kalpoe, 21, or Satish Kalpoe, 18, nor fellow detainee Joran van der Sloot, 17, the son of a justice official from Holland, aboard the boat. A brochure for the boat says patrons must be 18 or older.

“I’ve never had problems with him,” Wiggins said of Croes. “He keeps to himself and shows up to work every day and does his job.”

Wiggins said Croes had worked for the boat “for a period of time,” but could not say how long exactly.
