Man, 23, charged in plot to kill baby

Allegedly urged girlfriend to put meds in bottle

MATTHEW LEBLANC | The Journal Gazette

A Fort Wayne man is charged with conspiring with his girlfriend to kill an 11-week-old girl by putting headache medicine in the girl's bottle last year.

Sir Marshall S. Snyder III, also known as Marshall Snyder, repeatedly told Sarai Rodriguez-Miranda, 20, to kill the infant – her niece – in text messages and messages sent through Facebook, a probable cause affidavit alleged.  

Snyder, 23, also helped Rodriguez-Miranda flee to Michigan after police were called to investigate the plot to kill the girl in January 2017, court documents said.

He was charged July 25 with aiding attempted murder, but a judge sealed charging documents after prosecutors cited publicity the case would likely receive. The records were unsealed Aug. 8, according to Allen Superior Court records.

Rodriguez-Miranda admitted to trying to kill the girl and was sentenced in May to 25 years in prison. Angry that her mom allowed her brother, his fiancée and the baby to stay at their home longer than expected, she hatched a plan to put acetaminophen and sleeping pills in the child's bottle.

She discussed the plan with Snyder through Facebook and in text messages that were discovered by her mother, according to the affidavit.

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

More than 2,200 milligrams of acetaminophen was found in the bottle, according to court documents. Just 900 milligrams would have killed the girl, a forensic toxicologist told police.

The bottle of breast milk laced with the drug was discovered before it was given to the child. The girl was not injured.

“She is everything to me,” the girl's mother, Faythe Grosjean, said in a statement read at a sentencing hearing for Rodriguez-Miranda. “I don't know what I would do without her.”

Rodriguez-Miranda and Snyder exchanged chilling messages about killing the baby days before the medicine was added to the bottle, police said.

“Omg, id totally put anthrax in their baby formula if I could ... Or rat poison even,” a message to Snyder on Jan. 8 states, according to the affidavit. “Ugh that'd be the best thing ever if their baby died.”

Four days later – after he allegedly suggested his girlfriend stab her brother – police say Snyder responded to messages that said Rodriguez-Miranda put the drug in the bottle with, “cool.”

“Yeah, I thought it was funny that I don't have an ounce of guilt,” she wrote, according to the affidavit.

“woo hoo,” Snyder allegedly responded.   

The couple left Fort Wayne and went to Michigan, where U.S. marshals arrested Rodriguez-Miranda. She was charged in September with attempted murder.

A counsel status hearing is scheduled today for Snyder.
