Missouri Governor Jay Nixon has vetoed or frozen more than $1.1 billion of spending in Missouri's next budget.
Those withholdings mean devastation for the state's Department of Mental Health, including its Hannibal office.
Debra Walker is a spokesperson for the Missouri Department of Mental Health.
She said the Developmental Disabilities Regional Office in Hannibal will lose 12 positions and will be managed by the St. Louis Regional Office.
The remaining staff in Hannibal will continue to work at their current location to perform critical services such as eligibility determination, quality enhancement, contract provider monitoring, service coordination, consumer advocacy and crisis services.
Missouri's Department of Mental Health budget for fiscal year 2015 was reduced by about $34 million.
Tuesday's budget actions include a reduction of $1.5 million and 66 regional office staff positions across the state.
Walker said the management of these offices will be transferred to the remaining Developmental Disabilities Regional Offices.

Nixon's budget cuts announced Tuesday include nearly $276 million of line-item vetoes and $846 million of spending restrictions affecting everything from public education to Medicaid, citing concerns about declining revenues and the potential for new tax breaks.
The Democratic governor said his actions were necessary because the budget passed by the Republican-led Legislature was "dangerously out of balance."
