15 years given in baby-poison plan

January 16, 2019

A Fort Wayne man who conspired with his girlfriend to kill an 11-week-old girl by putting headache medicine in her bottle was ordered Tuesday to spend 15 years in prison.

Sir Marshall S. Snyder III, 23, also known as Marshall Snyder, had been charged with aiding attempted murder in the plot but pleaded guilty last month to aiding attempted aggravated battery. He was sentenced in Allen Superior Court.

“I’m very, very sorry,” Snyder said in court. “I wish I could take it back.”

He and Sarai Rodriguez-Miranda, 20, plotted to kill the infant in January 2017 by lacing a bottle of breast milk with more than 2,200 milligrams of acetaminophen. Just 900 milligrams of the drug would have killed the girl, a forensic toxicologist told investigators.

Rodriguez-Miranda was angry her mother allowed her brother, his fiancée and the baby to stay at their home longer than expected, according to court documents. Snyder repeatedly told his girlfriend to poison the girl : her niece : in text and Facebook messages.

The plans were discovered by family members, and the bottle was not given to the girl. She was unharmed.

A plea agreement with prosecutors filed in December called for Snyder to spend 15 years behind bars, but the baby’s mother asked Allen Superior Court Judge Fran Gull to hand down the maximum sentence for the crime: 16 years.

“He thought what (Rodriguez-Miranda) was doingwas funny,” Faythe Grosjean said in a statement read by a victim advocate Tuesday in court. “I don’t know why he would do this to Alivia. He didn’t even know her.”

Snyder, dressed in a jail-issued orange jumpsuit, offered no explanation.

David Rigby, the infant’s grandfather, said Snyder had a chance to stop the crime.

“Instead, he chose not to stop it,” he said. “He knew what he was doing. He did nothing.”

Rodriguez-Miranda pleaded guilty to an attempted murder charge and was sentenced in May to 25 years in prison.
