MASON CITY — A man whose name became widely known across Northern Iowa during a sensational child-murder trial more than a decade ago is back in the Cerro Gordo County Jail, this time accused of domestic abuse assault and interfering with police.
Michael Jason Cisneros (pictured at top), 50, was booked into the county jail at 4:14 a.m. Sunday, August 2, 2026.
Jail records list the following charges:
- Domestic abuse assault, third or subsequent offense
-
Interference with official acts without injury or damage
A $300 cash or surety bond was listed on the interference charge. Cisneros was being held in the jail’s intake-detox area following his arrest.
Details surrounding the alleged domestic incident, including the identity of the alleged victim and what reportedly happened before police arrived, were not immediately available.
Cisneros is no stranger to the Cerro Gordo County criminal justice system or readers of NorthIowaToday.com.
He was charged in 2013 with first-degree murder in the death of 20-month-old John Joseph Snyder Jr., whose body was discovered in Willow Creek in Mason City on July 21, 1994.
The child had disappeared from a Mason City apartment the previous day. His pajama bottoms and diaper were later recovered along the creek, and investigators said an autopsy determined he died from drowning and a crushing skull injury.
The cold case remained unsolved for nearly two decades before authorities alleged that DNA evidence connected Cisneros to the child’s pajama bottoms.
NIT covered the prosecution extensively, including the beginning of Cisneros’ first-degree murder trial in June 2014.
Despite the evidence presented by prosecutors, a Cerro Gordo County jury acquitted Cisneros of first-degree murder on July 14, 2014. Court records list the charge as dismissed by jury acquittal, meaning Cisneros cannot be described as guilty of the child’s death.
Hours after the verdict, Cisneros personally reached out to NIT and offered an exclusive interview.
At the time, Cisneros said he had left Mason City to be with his family and was attempting to process the ordeal.
“Right now I am just enjoying being with my family,” Cisneros told NIT shortly after the jury cleared him.
NIT Publisher Matt Marquardt later spoke with Cisneros for nearly two hours. Much of that conversation remained off the record, but Marquardt shared his impressions in “A conversation with Michael Cisneros.”
Cisneros maintained his innocence throughout the case, and the jury’s verdict left the brutal death of John Snyder Jr. without a convicted killer.
In the years since that trial, Cisneros has encountered law enforcement elsewhere in Iowa.
Court records show he was arrested by Iowa Falls police in October 2025 for possession of drug paraphernalia. He entered a negotiated guilty plea and was assessed $180.75 in fines, surcharges and costs. Records later showed the unpaid portion of that debt was sent to county attorney collections.
Cisneros also has a prior assault conviction stemming from a November 2019 incident in Jackson County.
He was originally charged with assault while displaying a dangerous weapon. In September 2020, he entered a negotiated guilty plea to assault with intent to inflict serious injury and was sentenced to 100 days in jail and a $625 fine.
Financial records in that case show he was assessed a total of $1,446.13 in fines, surcharges and court costs.
More recently, Mason City police cited Cisneros on July 2, 2026, for allegedly operating a vehicle with a dark window or windshield. That scheduled-violation case remained pending in Cerro Gordo County court records.
The latest allegations return Cisneros to the same county jail where he was once held on a $500,000 cash bond while awaiting trial in one of Mason City’s most disturbing and closely watched murder cases.
The new charges are accusations only. Cisneros is presumed innocent unless proven guilty in court.
