Three Utahns died in separate traffic accidents this weekend, Utah Highway Patrol officials said.
DEAD:Robert Todd Welcher, 3, South Salt Lake
Ralph Siems, 66, Kearns
Mario Rodriguez, 29, Hanksville
Welcher was hit by a car outside his baby sitter's house at 1969 S. West Temple about 1:10 p.m. Saturday. He had darted between parked cars, apparently trying to cross the street to play in a grassy area on the other side of West Temple.
Welcher was taken to Primary Children's Medical Center with head injuries, where he died at 10:43 p.m. Saturday. No action was taken against the driver of the car, police said.
Siems was southbound on I-15 at 78th South in Salt Lake County about 10 p.m. Saturday when his vehicle drifted into another vehicle traveling the same direction in an adjacent lane, a UHP spokeswoman said.
Siems' vehicle began to slide after the impact, striking and then flipping over a guardrail. The vehicle rolled down an embankment and ejected Siems, who was pinned underneath it.
The driver of the second vehicle involved stopped but then left the scene of the accident before being identified, witnesses told the UHP.
Rodriguez was killed when the Utah Department of Transportation dump truck he was driving two miles west of Hanksville on U-24 Friday crossed the center line, causing him to over-correct.
The dump truck left the roadway and rolled three times, a UHP spokesman said.
Rodriguez was pronounced dead after paramedics performed cardiopulmonary resuscitation on him for about 30 minutes, the spokesman said.
