The Dominican Republic's minister of the environment and natural resources - the son of a former president - was shot to death in his office by a close friend, the office of the president said in a statement.
Authorities said Orlando Jorge Mera was shot by Miguel Cruz, who had been detained. Officials gave no motive, and it wasn't immediately clear if Cruz had an attorney.
"We express our deepest condolences," the office of President Luis Abinader said.
Heavily armed police officers quickly escorted Cruz out of the building after the shooting. He was wearing a helmet and bulletproof vest and kept his head mostly down as the glasses he wore slid slightly down his nose. One bystander yelled: "You killed a good man! Murderer!"
The victim came from a powerful political family. Jorge was the son of former Dominican President Salvador Jorge Blanco and his sister is a vice minister in Abinader's administration. Jorge's son is a lawmaker for the Modern Revolutionary Party, of which Jorge was a founding member.
