HARRIS COUNTY, Texas -

The Harris County Sheriff's Marine Unit continued conducting a search Sunday for two teenagers who disappeared after the truck they were in crashed into the bayou.

Deputies searched the five mile stretch of the bayou from Fairbanks North Houston to Antoine Drive on foot and jet skis as helicopters scanned the waters as well, looking for 18-year-old Eric Cabrera and 17-year-old girl who has not been named.

The Sheriff's department said a witness called 911 around midnight Friday night, reporting a vehicle had left the roadway along Fairbanks North Houston and gone over the embankment near Emmott.

Emergency crews responded immediately, but swift currents kept divers from going into the water to search for the driver and passenger who had been inside.

Sheriff's officials say a man driving in the area saw the pick-up truck skid off the road and into the bayou. The man told officials he saw the two teens hanging onto the truck. The man ran to grab a wench line to pull them out, but when he returned the teens were gone.

Officials say White Oak Bayou was about 20 feet deep and the current was moving roughly 30 mph.

"The current is so strong we can't launch a boat here, because the banks are so steep and the current is so bad," said Sgt. Doug Hudson.

As of Sunday night there was still no sign of the two teenagers.
