The Mason City Police Department has made an arrest in a 19 year old murder thanks to DNA technology.

Officials announced Monday that 37-year-old Michael Jason Cisneros has been charged with first degree murder in the death of 20-month-old John Joseph Snyder Jr.

Snyder went missing from his father’s apartment on July 20th, 1994. His pajama bottoms and a diaper were found later that day along Willow Creek.

Snyder’s body was located the next day in Willow Creek. An autopsy showed he died of drowning and a crushing skull injury.  His death was ruled a homicide.

Police say a DNA analysis of the evidence in the case wasn’t done in 1994 because the technology wasn’t available at the time. The evidence was submitted in 2002 and a DNA match to Cisneros was made in January of 2013. His DNA was found on Snyder’s pajama bottoms. Cisneros had been forced to submit a DNA sample to the state in 2012 because of a felony conviction.
