SALT LAKE CITY — Police say a 4-month-old suffered two broken legs, which led to the arrest of a Salt Lake couple Monday.

Lorissa Boltinghouse, 30, and Jeremy Johnson, 28, were booked into the Salt Lake County Jail for investigation of intentional child abuse. The injuries were discovered by doctors after the infant was taken to Primary Children's Medical Center. The girl had two broken legs and a torn frenulum, or tissue under the mouth.

Boltinghouse, the baby's mother, "admitted to yanking the child's legs and forcing a bottle into its mouth," according to a Salt Lake County Jail report.

The father, Johnson, also admitted to forcing the bottle in the infant's mouth, the report states.
