Man takes plea deal in scheme to kill infant

December 29, 2018

A Fort Wayne man charged with aiding attempted murder for conspiring with his girlfriend to kill an 11-week-old girl has pleaded guilty to a lesser charge.

Sir Marshall S. Snyder III, also known as Marshall Snyder, pleaded guilty Dec. 21 in Allen Superior Court to aiding attempted aggravated battery. A plea agreement calls for him to spend 15 years in prison.

The aiding attempted murder charge will be dropped when Snyder, 23, is sentenced Jan. 15, according to the agreement.

Snyder and Sarai Rodriguez-Miranda, 20, plotted to kill the infant in January 2017 by putting headache medicine in her bottle. The bottle of breast milk laced with more than 2,200 milligrams of acetaminophen was discovered before it was given to the girl, and she was not injured and remains with her mother.

Just 900 milligrams of the drug would have killed the girl, a forensic toxicologist told police.

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

“Look up how many mg can kill a baby,” one message from Snyder said, according to a probable cause affidavit. “Haha.”

Rodriguez-Miranda admitted trying to kill the girl and was sentenced in May to 25 years in prison.
