Police have identified a man killed in a fiery crash with a semitrailer Thursday evening.

Martin Aguilar, 40, was killed around 5:30 p.m. when the semi collided with another vehicle and swung in front of Aguilar's pickup on state Route 111 near 5400 South, the Salt Lake County Sheriff's Office reported.

The pickup ran off the road and burst into flames, trapping Aguilar inside.

A man driving another pickup truck caused the crash, police said, when he made a U-turn in front of the semi.

Sheriff's officials did not know where Aguilar is from.
