(CNN) -- Florida investigators on Thursday named a suspect in the slaying of two children whose bodies were found stuffed in luggage and floating in a south Florida canal, a police spokeswoman said.
The suspect's name is Clem Beauchamp, according to Delray Beach Police Sgt. Nicole Guerriero. She said investigators are currently searching a house in connection with the case.
She refused to provide further details, including the names of the victims.
Attempts to contact Beauchamp Thursday were unsuccessful.
Guerriero told reporters earlier that the victims are believed to be a brother and sister, and their deaths appear to be "domestic-related." Detectives were trying to confirm the tentative identifications Thursday afternoon.
"We are following up leads to confirm that we have them ID'd, and that what we believe is true," she said. But she added that detectives are fairly confident with what they have found.
The two African-American children -- a girl between 6 and 10 years old, and a boy believed to be 10 to 12 -- were found Wednesday about six hours and a half-mile apart in the canal that separates Delray Beach from Boca Raton. The girl's body was found first, after a passerby alerted police to a duffel bag floating about midway across the canal; the boy's body turned up in a suitcase closer in as investigators combed the banks for evidence, Guerriero said.
"We're devastated, and someone is missing these children," Guerriero told reporters Wednesday evening. "Someone knows these children, and we need to know who these kids are."
Investigators returned to the banks of the canal for a more extensive search Thursday, and the bodies were slated for autopsies, but Guerriero said no results from those procedures had come back Thursday afternoon.
