SHAMOKIN - Northumberland County Coroner James F. Kelley said an autopsy Tuesday morning on the 11-week-old boy who died Monday in Shamokin did not reveal anything suspicious.
"There was no bruising noted on the baby that would concern us," he said Tuesday afternoon from the Shamokin Police Station.
He referenced a mark on the baby's head that was described as "a bruise or discoloration" in an affidavit accompanying a search warrant sought and obtained by Shamokin Police on Monday.
"There was a mark on the forehead, but there was no underlying hemorrhaging" related to that mark, Kelley said.
Kelley said complete results of the autopsy will take 18 weeks, three weeks longer that adult autopsies because of additional testing that is done on infants. Toxicology tests and those that check for bacteria and viruses, as well as spinal fluid, will be conducted. X-rays that were taken will be reviewed by a pediatric specialist at Hershey Medical Center, Kelley said.
Emergency medical services personnel and police were dispatched to 349 S. Market St. at 10:28 a.m. Monday for a cardiac arrest call. The baby, Navaydius D. Marciniak, was pronounced dead at 11:15 a.m. at Geisinger-Shamokin Area Community Hospital.
Police spent hours at the house, interviewing the parents, Damon Marciniak, 18, and Turqoise Johnson, 20, and others. They removed bedding from the home.
Johnson lives in Lewisburg but was at the Shamokin home when the death occurred.
The parents told police they woke to find Navaydius' 15-month-old brother lying partially on top of him. The boys were sleeping on the floor with a third brother, age 2, in the same room with the parents, police said. Navaydius wasn't breathing, the parents said, and Marciniak and his aunt and uncle performed CPR while 911 was called.
Dr. Michael Johnson performed the autopsy on Navaydius starting at 7:45 a.m. Tuesday at Lehigh Valley Hospital, Allentown. Kelley and investigating officer, Shamokin Patrolman William Miner, were present, the coroner said.
Kelley said he and family are interested to learn the results of this testing because a girl, Jahniyah Turner, from the same family died two years ago at 6 months.
Jahniyah's cause of death was listed as sudden death of an infant while co-sleeping with an adult.
Kelley said they'll compare records to see if there's any genetic correlations between the deaths of the two children.
The two children do not have the same parents, Kelley said.
