It was a tearful separation for brothers Brandon and Darrion Roopnarine on Sunday night, as family members were unable to honour their wish to stay together.
Brandon Roopnarine, nine, moved out of his father's home at Penal Rock Road to live with his biological mother.
Darrion Roopnarine, five, will remain at the house in care of his aunt.
The children's lives were shattered two Sundays ago when a car ploughed into their father, Khemchan Roopnarine, and his wife, Patricia Harripersad.
The two were walking home after spending the evening at a relative's house.
The boys were walking ahead of them.
Police said the couple were two houses away from their home when a white Nissan Tiida car slammed into them around 10 p.m.
Roopnarine, 38, and his 36-year-old wife were thrown at the side of the road. The car sped off.
The couple died at the scene.
The incident was witnessed by the two boys and several persons standing on the roadway.
Roopnarine's relatives are now pleading with the driver to surrender himself to police.
His cousin, Seudath Roopnarine, said: “It is time for the driver to give himself up to police. Look at what has happened. These people died. These children are separated. An entire family destroyed.”
Police detained the owner of the car last Monday.
The 40-year-old schoolteacher said a male friend had borrowed the car that day and returned the damaged car without an explanation.
The woman gave investigators information on the driver and police have since launched a manhunt.
The Express was told the man is known to police as he was previously charged with a criminal offence.
Roopnarine's relatives have also appealed to anyone with information on the man's whereabouts to contact the police.
