A West Valley City woman was arrested Tuesday after being charged with the death of her 1-year-old son. Officers confronted Mesepa Heimuli, 28, outside her home near 2200 West and 3800 South around 4 p.m., said police Capt. Tom McLachlan.
   Heimuli is accused of inflicting head injuries to Uatisone Sua Jr., causing his death on Dec. 2, 2006. Because Heimuli was pregnant at the time, she was not arrested. The Salt Lake County jail has a policy not to accept women pregnant in their third trimester, said Lt. Paul Jaroscak.
   "We just don't want to have to worry about delivering babies in jail," Jaroscak said.
   Heimuli gave birth about two weeks after the toddler's death, McLachlan said. Investigators considered her a suspect from the start but were cautious in how they built the case, said McLachlan. She also did not appear to be a flight risk or danger to the public, he said.
    Heimuli had two other young children at the time of Uatisone's death. Both were immediately placed into protective custody with a relative said Dwayne Bourtenay, director of the Utah Division of Child and Family Services. Heimuli's newborn child was also taken from her and placed with family following the birth, Bourtenay said.
