Pregnant Tourist Alanna DeMella's Death At Riverside Hotel May Be DUI Case

Police believe the driver who killed a pregnant tourist last month by crashing into a pool cabana at Fort Lauderdale's Riverside Hotel may have been drinking before the accident.

Rosa Rivera Kim, 34, was at nearby restaurant Mangos for a drink before losing control of her vehicle and slamming into the cabana Massachusetts resident Alanna DeMella, 26, had entered to use the restroom,according to Local 10.

DeMella, who was on a church-sponsored vacation with her husband, was seven months pregnant with the couple's first child.

Kim told officers at the scene that though she had a martini with appetizers at Mangos, she left after an argument with her husband and didn’t finish her drink, The Boston Channel reports.

"There is probable cause to believe that Rosa Maria Rivera was under the influence of an alcoholic beverage and/or controlled substance at the time of this crash," read court documents. Results of Kim's blood test, taken shortly after the crash, are not yet known.

According to CBS Miami, witnesses also said Kim appeared to be traveling faster than the 25 mph speed limit on Las Olas Boulevard.

After DeMella's death, her husband formed the Alanna DeMella Missions Fund through the couple's church to help fund missions trips.
