CHICAGO (AP) -- One of two victims killed in yesterday's truck crash at the Chinatown Chicago Transit Authority station was a longtime employee of a downtown hotel.

Forty-seven-year-old Elosia (Elo-EE'-saw) Guerrero worked in room service at the Sutton Place Hotel and was at the station after work.

Her coworkers say she was a sweet and outgoing woman.

The Cook County medical examiner identified the other victim as 18-year-old Delisia Brown.

The accident left 21 injured but by Saturday afternoon at least three remained hospitalized. All were in fair condition.

Meanwhile, Mayor Richard Daley says authorities are trying to determine how fast the truck driver was traveling.

He says his thoughts are with the families of the victims.
