Kleine said Lopez’s probation is open-ended, so if the judge decides, probation could continue until Lopez turns 19. Lopez turns 17 in June.

Police have said that after Lopez threw the baby outside, her mother found the baby and, “distraught and frantic,” called 911 at 4:12 a.m. She performed CPR on the baby until paramedics and police arrived.

The baby and Lopez were taken to Creighton University Medical Center, where the baby was pronounced dead upon arrival.

The child was about 14 inches long and weighed 2 pounds.

An autopsy later determined that Lopez had been pregnant for 25 to 28 weeks — about the seventh month of gestation.

In a Snapchat message to her boyfriend, Lopez wrote, “It was a girl by the way.”

The autopsy revealed that the baby suffered bleeding near her skull, brain, spine and abdomen. The pathologist told police that the bleeding indicated that there was a heartbeat — the baby was alive when the blunt-force injuries were sustained.

Lopez told a police detective that she had not known she was pregnant and woke up in pain. She said she laid a towel on the floor of her bedroom because she thought she was having her period. Lopez’s boyfriend disputed her assertion that she didn’t know she was pregnant. An Omaha police officer said the boyfriend told him that he had urged Lopez to tell her mother about the pregnancy and see a doctor, but she didn’t.
