A 41-year-old Davie man remained jailed on murder charges Monday after police say he drove over a groundskeeper with his Mercedes in Dania Beach.

Issa Asad, 41, is accused of running over Michael Kramer, 50, of Hollywood, at 499 Sheridan St. on July 5.

Witnesses told detectives that Kramer and a helper had finished some groundskeeping on the property when Asad, the property owner, arrived. As Kramer stood in front of Asad's black four-door Mercedes S550, the two argued over $65 Kramer said Asad owed him, according to detectives.

Asad began inching the vehicle forward, and Kramer said, "Are you going to run me over?" according to detectives. Asad then said, "If you don't move, I'm going to run you over."

Then, witnesses said, Asad stepped on the gas, running over Kramer, according to detectives.

Asad called 911 from a cell phone and repeatedly told the operator "he had an altercation and the victim jumped in front of his car and was attacking his car," according to a court document.

Kramer never regained consciousness, according to detectives. He died of his injuries July 15.

Asad was originally charged with aggravated battery with a deadly weapon, but that charge was changed when Kramer died, according to detectives. Asad is being held without bond pending trial.
