Two Rhode Island men were arrested for allegedly murdering a pregnant woman from Brockton, and one of them is the father of the unborn child, according to Rhode Island State Police.

Da Luz’s body was recovered in December submerged in Carbuncle Pond in Coventry, Rhode Island, police report. The State Medical Examiner ruled her death a homicide, and police say they were able to identify her Dec. 27, a week after she was found, from a missing person’s report in Brockton.

In the resulting investigation, police say they executed 53 search warrants involving evidence pertaining to the murder. Police report they were able to use the warrants and interviews to arrest the two suspects.

Multiple units within the Rhode Island State Police assisted in the process, as well as Brockton police and several other agencies.

Colonel Darnell S. Weaver, superintendent of the Rhode Island State Police and director of the Department of Public Safety, said he was grateful for the collaborative effort.

“I want to commend our Troopers and partners in law enforcement for their exceptional diligence and hard work in pursuit of justice for Ms. Da Luz,” he said in a statement. “On behalf of the Rhode Island State Police, I extend my condolences to the loved ones of Ms. Da Luz at this difficult time.”
