New York ? An amusement park worker killed on a ride was among the riders imploring the operator to get the ride going instead of at her post monitoring an emergency shut-off switch, police said Monday, citing witnesses.

Investigators also found in a preliminary probe that 21-year-old Gabriella Garin, who had worked for seven years at Playland in Rye, about 25 miles north of midtown Manhattan, probably was not wearing her seat belt, Westchester County police Commissioner Thomas Belfiore said.

Garin was killed Friday night at Playland, the landmark county-owned park in Rye, when she was ejected from the Mind Scrambler. It was the second death on the ride, and the third on a Playland ride, since 2004.

Belfiore said about 10 witnesses indicated that Garin “was not secured in the car and that when the ride started she knelt on the seat. Some witnesses say she then stood on the seat and then fell from the ride.” When she fell, within 30 seconds of startup, she was struck by the speeding, spinning cars, he said.

The special booth with a cutoff switch was installed after the first death on the ride, which is owned and operated by S&L Amusements.
