Divers have found the bodies of 15 women, one man and a toddler, while another 20 men and five women have been rescued since Sunday, according to Bahamian officials.

The U.S. government is helping with the ongoing search as local authorities deploy drones, planes and submersibles, said Capt. Shonedel Pinder, deputy commander of the Bahamas Defense Force.

“It’s a combined effort using all available resources...to see if there are any potential survivors...as well as to recover any remains,” he told reporters.

Two Bahamian men are in custody, although it wasn’t immediately clear if they have been charged as officials launch a criminal investigation into a suspected human smuggling operation.

The twin-engine speed boat named “Bare Ambition” apparently capsized about seven miles from New Providence after leaving the Bahamas around 1 a.m. on Sunday, likely bound for Miami. It became the latest deadly voyage for Haitian migrants as they flee a deepening economic crisis and a spike in gang-related violence in their country, which is struggling to recover from the assassination last year of President Jovenel Moïse.

In May, at least 11 people died and 38 others were saved near Puerto Rico, while another boat carrying 40 migrants went down near Florida, with only one man rescued and another found dead.
