GRAND RAPIDS, Mich. (WOOD) — Months after a baby died of head trauma in Grand Rapids, his father has been charged with murder.

Abdullah Muhammad, 21, was arrested Tuesday and arraigned Wednesday on charges of felony murder and first-degree child abuse in the death of his son, Daylin Aromon Muhammad.

Emergency responders were called to a home on Burton Street SW near S. Division Avenue on the evening of Jan. 15 on a report of a 2-month-old boy who wasn’t breathing and turning blue, court documents show. Crews were able to get the baby to breathe again and rushed him to a hospital. There, doctors discovered head injuries “consistent with abuse and repetitive trauma,” the documents say.

Daylin died at the hospital on Jan. 31. He was not yet 3 months old.

The medical examiner ruled his death a homicide, calling the injuries “traumatic.”

Court documents said Daylin’s mother left him with his father while she picked up dinner. When she returned about half an hour later, she told investigators, she found Muhammad holding Daylin, who was choking and turning blue.

Muhammad told investigators that he fed the baby formula and that the baby started to cry and spit up a lot. He said he tried changing the baby.

“Abdullah stated he thinks this is where he made a mistake by laying (Daylin) down while he was spitting up and choking,” the document reads.

The document says Muhammad told investigators he tried breathing into the baby’s mouth to clear the fluid and picked him up, but Daylin kept crying.

“Abdullah stated he thought (Daylin) was calming down a bit and eventually noticed he appeared weak and his arms were limp,” the document says, going to to say Muhammad also described the baby’s breathing as labored.

When the baby’s mother returned home, they called 911.

“When advised of (Daylin’s) head trauma injury, Abdullah was not able to explain how (Daylin’s) injuries occurred,” the document said.

The Grand Rapids Police Department said detectives conducted a “lengthy investigation.” The court documents say GRPD got a report from the Center for Child Protection that included an opinion from a doctor saying Daylin could not have caused the injuries to himself and diagnosing abuse.

A warrant for Muhammad was signed June 10.

“This is an example of the determination and commitment of GRPD detectives,” GRPD Chief Eric Winstrom said in a statement. “Throughout these months of investigation, detectives did not waiver in their commitment to bring justice for this child.”

Bond was set at $200,000.
