Indianapolis police are investigating the death of a 2-year-old girl who died at Methodist Hospital early Wednesday morning of unknown causes. Police were called to the child's home in the 200 block of Parkview Avenue on the near-east side just before midnight Tuesday because the girl had stopped breathing. The child's aunt, Irene Glenn, said the child had fallen and hit her head earlier in the day. An autopsy scheduled for Wednesday or early Thursday morning will determine an exact cause of death.
