An officer-involved shooting Sunday in Hallandale Beach ended with a man dead, police said Tuesday.

It began when an officer spotted a man who matched the description of a “be on the lookout” alert sent by the city of Aventura, said Hallandale Beach Police Chief Dwayne Flournoy. The description was of a person connected to a theft from the Best Buy store in Aventura, Flournoy said.

The officer saw the man, identified Tuesday as Gregory Ehlers, 34, of the New Port Richey area, near Hallandale Beach Boulevard and U.S. 1. The officer tried to stop him, Flournoy said, but the man ran away.

More officers came, and continued the search. Then, Flournoy said, an “alert bystander” told them there was a person on the roof of a one-story duplex in the 400 block of Northeast Fourth Court.

Officers “tried to have the person come down,” he said, but Ehlers refused.

“There came a time one of the officers felt in fear for his life,” Flournoy said. “He discharged his firearm, striking the person on the roof.”

Flournoy said Tuesday night he did not know what exactly Ehlers did to make the officer feel in danger. The officer who fired, Edward McGovern, had yet to give investigators his formal account of what happened.

Ehlers was taken to Memorial Regional Hospital in Hollywood, where he died.

On the roof, Flournoy said, investigators found electronics items believed to have been taken from the Best Buy store.
