BOWLING GREEN, Mo., Sept. 14 (UPI) -- For the second time in three weeks, a baby has died in Missouri after mistakenly being left inside of a car during a day with 80 degree temperatures.

Police in Bowling Green, Mo., said a 4-month-old girl's father apparently left the baby in the back seat of his car Thursday, only to find his child had died due to high temperatures, The St. Louis Post-Dispatch reported Friday.

Capt. David Oney would not confirm whether charges would be filed against the unidentified baby's 30-year-old father.

"We've just (started) the investigation," Oney said. "We've got a lot of work to do."

A similar tragedy occurred Aug. 23 in St. Louis, when 7-month-old Sophia Knutsen died after being left in her parents' car. Each parent had thought the other was taking care of the child, who was left trapped in a Washington University School of Medicine parking lot.

Prosecutors are still weighing criminal charges in that case, the Post-Dispatch said.
