Havana, May 22 (RHC)-- The 33-year old driver of the car that killed five people along Havana’s seafront drive was under the influence of alcohol and speeding, Cuban authorities said Tuesday.

In a press conference with local media, Cuba’s National Transit Commission shared results of preliminary investigation of the deadly crash.

The American classic car, a 1952 Mercury, was driving in the middle lane along Malecon Avenue when it went onto the sidewalk and hit more than 20 people before crashing into the famous seawall, said Lt. Col. Jesus Aguilar, head of traffic for the criminal operations division.

So far, five people have died and 18 remain injured, including two Americans who were transferred by air ambulance to Fort Lauderdale Monday night.

Besides the driver’s responsibility, the officials disclosed that the car’s break system was deficient, and that the vehicle had not been subjected to technical inspection since 2007.
