BARSTOW Two Gardena men were killed at about 4 a.m. Thursday after their 2005 Honda rear-ended a tractor trailer on northbound Interstate 15 near the Lenwood Road off-ramp.

A third passenger was taken to Antelope Valley Hospital with moderate injuries, according to the California Highway Patrol. The driver Rene Rivas, 42 and unidentified injured passenger had been wearing their seat belts at the time of the crash. The deceased passenger Kevin Okada, 36 also of Gardena, had not been wearing a seat belt.
