Alicca Williams, 24, is charged with the Class C Felony Reckless Endangerment of a Child, from a crash that happened on January 6.
In the early morning on January 6, prosecutors say Williams was heading southbound on Route C east of St. Joseph.
Under wintry conditions, troopers on the scene say Williams lost control of her car and hit a snowplow that was going northbound.
That crash injured her one year old son Kaiber Williams, who later died from his injuries.
Prosecutors say Williams' son was sitting in the front seat unrestrained at the time of the crash.
At her appearance in Buchanan County Division 5 Judge Keith Marquart's courtroom Tuesday morning, assistant prosecuting attorney Kate Schaefer brought to light that at the time of the crash earlier this month, William had warrants for arrest on two other charges.
Both of the prior charges are also traffic charges; one is related to another crash from 2010, when Williams allegedly struck another vehicle and was found to not have proper insurance.
Given her prior charges, and the nature of the current charges, Judge Marquart told the defendant that she "shows a complete lack of responsibility," and denied the defense attorney's request to reduce Williams' bail.
Her bail is currently set at $30,000.
Williams will remain in custody, unless that bail is posted.
The defense attorney did tell the court that she and her client plan to plea not guilty at a future appearance.
Williams will appear next for a preliminary hearing on February 7.
