MIAMI -

Opening statements began Monday in the trial of a former Miami Beach police officer charged with four felonies stemming from a 2011 beach crash in which the all-terrain vehicle he was driving struck and seriously injured two people.

"He drove recklessly. He drove without headlights," prosecutor Eileen Keeley said of Derick Kulian. "He struck two people, and his actions that night shattered the lives (of the victims)."

Prosecutors said the crash happened when Kuilan was joy-riding with a woman on the ATV after drinking while on duty at a South Beach nightclub bachelorette party during Fourth of July weekend 2011.

A man and a woman walking on the beach to see the sunrise were injured.

One of the victims, Luis Almonte, took the stand Monday. Almonte, who has a metal rod in his leg, said he didn't see any headlights or have any warning that the ATV was coming.

Then-bachelorette Adalee Martin Jones and maid of honor Camille Hippensteel also testified.

Jones said she thought it would be fun to take a ride on the ATV.

"I made a comment, 'The uniforms look so tight, they almost look like strippers,'" Hippensteel testified.

Kulian's colleagues drew his blood, against his will, defense attorney Evan Hoffman claims, that showed he had a blood-alcohol level of 0.088, which is above the legal limit.

Kuilan is charged with two counts of driving under the influence with serious bodily injury and two counts of reckless driving with bodily injury.
