Shelby Dasher, the mother of Tyler Dasher, a dead 1-year-old Missouri boy, was charged with second-degree murder on Wednesday and is being held on $500,000 cash bail
Authorities also said the 20-year-old mother is on suicide watch, according to ABC News.
Prosecutors said the Shelby Dasher admitted to beating her toddler son because he wouldn't stop crying. She was arrested less than 16 hours after reporting her son missing from his crib.
Tyler Dasher's body was found Tuesday near a cemetery about a mile from the Dasher home.
Police responded to a call about a missing child around 11 a.m. Tuesday and was told the child was last seen at 10 p.m. the day before. Shelby Dasher told police she overslept Tuesday morning and when she woke up and saw her son gone, she called the cops, according to the Post-Dispatch.
People walking their dog found Tyler Dasher's body around 3:30 p.m. on Tuesday in a wooded area about one mile from his home, police said, noting that a medical examiner confirmed the remains belonged to the toddler.
Shelby Dasher was arrested early Wednesday, a day after her son's body was discovered near the edge of the New St. Marcus Cemetery.
St. Louis County prosecutor Bob McCulloch told The Associated Press that Dasher admitted to police that she repeatedly hit her son because he was crying and wouldn't lay down, wouldn't go back to sleep.
Shelby Dasher also admitted to police that she disposed of her son's body in a nearby graveyard in St. Louis County, Mo.
McCulloch told the media that a medical examiner has said Tyler Dasher died from multiple blunt force trauma to the head. He added that no objects seem to have been used. The medical examiner didn't find any sings of past abuse on the toddler.
Raising children can be frustrating, McCulloch told the media. There are a myriad of ways to handle that. This isn't one of them.
Shelby Dasher had told police she was out part of the night and early morning before her son went missing.
McCulloch said Shelby Dasher's mother was at home all night but wasn't involved in the events leading up to the toddler's death.
The toddler and his mother didn't sleep in the same room, McCulloch added.
McCulloch told the media that Shelby Dasher is being charged with second-degree murder and not first-degree murder because of the lack of deliberation.
It's the difference between hot-blooded and cold-blooded murder, he said.
