BULLHEAD CITY, Ariz. -- Detectives in Bullhead City are investigating the death of a 7-month-old baby boy.

According to police, emergency crews responded to a home on the evening of April 9 after learning that a baby wasn’t breathing.

The child was rushed to Western Arizona Regional Medical Center and then flown to Sunrise Hospital in Las Vegas, Nev. where he was placed on life support due to a severe brain bleed.

The child, Richard Joshua Cromwell, was taken off life support on April 14 and died a short time later.

The medical examiner determined that Cromwell had suffered a skull fracture that was caused by blunt force trauma by assault.

Investigators began looking into Cromwell’s parents, while Child Protective Services took custody of the parents’ two-year-old daughter.

Authorities spoke with the father, 21-year-old Derek James Cromwell, and placed him under arrest for an outstanding misdemeanor warrant for assault and disorderly conduct per domestic violence against his wife during an incident back in February.

He has not been charged with a crime in connection to the death of his child.

“The Bureau of Criminal Investigations has been vigorously working on this investigation,” said Bullhead City Police Detective Mary Garcia. “We have conducted countless interviews and served a search warrant into the home of the baby’s parents. Investigations like these can be very time consuming and every effort is being made to identify and collect the evidence necessary to arrest the person(s) responsible for this heinous crime.”

Anyone with any information is being asked to call Detective Garcia at 928-763-1999.
