Jimani, Dominican Republic ? Sobbing villagers tore through heaps of mud with their bare hands Tuesday, searching for loved ones as the death toll from flooding in the Dominican Republic and Haiti rose to at least 363. Trucks dumped scores of corpses into a mass grave.

An Associated Press reporter counted at least 180 bodies on the Dominican side of Hispaniola island by Tuesday afternoon. Another 100 or so had been dumped in the mass grave, according to Lt. Virgilio Mejia with the Dominican National Rescue Commission.

There were 83 confirmed deaths on the Haitian side, but the toll in both countries was steadily rising.

“I’ve looked at the bodies in the morgue and couldn’t recognize any of them,” said Jude Joseph, 30, who came to Jimani from Haiti’s capital of Port-au-Prince to sell rice at a border market and visit family members in Bobmita, La Cuarenta and Barrio El Tanque, neighborhoods that were swept away in Monday’s floods.

“I don’t know what to do. I’ve been left with nothing,” said Joseph, whose nine relatives were missing late Tuesday.

They were among the more than 250 unaccounted for in the Dominican Republic. In addition, 62 were missing in Haiti, mostly in the town of Fond Verrette.

U.S. Marines, who are leading a 3,600-member multinational task force sent to stabilize Haiti since the ouster of President Jean-Bertrand Aristide on Feb. 29, headed to Fond Verrette help in the emergency.

Rain has pelted the region for weeks, but a weekend downpour caused the Solie River to burst its banks, sweeping away the three neighborhoods of wooden shacks built mostly by Haitian migrants working in this impoverished Dominican town. At least 50 of the dead on the Dominican side were Haitians.

“I found them this morning,” said Shela Lena, 24, who lost her sister-in-law and 3-year-old nephew Tuesday. She came from Port-au-Prince to work as a maid.

Rescue workers carry the body of a victim from the mud in Jimani, Dominican Republic, about 124 miles southwest of Santo Domingo. Floods unleashed by torrential rains swept through the town Monday, killing about 100 people and leaving dozens of others feared dead. Rescue and recovery efforts continued Tuesday.

About six miles outside of Jimani, emergency workers in surgical masks and white gloves watched as trucks dumped scores of corpses into a 15-foot ditch.

By late Tuesday, more than scores of bodies filled the grave. No relatives were present for the mass burial.

Some on the Dominican side were believed to be Haitian workers living there illegally and therefore afraid to claim the bodies of family members.

The Dominican government had issued an alert Sunday, warning people that rivers may swell with the rains. But Jimani, more than 100 miles west of the Dominican capital of Santo Domingo, only has limited access to radio broadcasts.

Elena Diaz, 42, who lost her daughter in the floods, sobbed as she waited in a long line outside the morgue where she went to look for her son-in-law and three grandchildren.

“They found my daughter. Now I have to see if I have some family left,” she said.
