Twin brothers have been found shot to death inside a vehicle in New Jersey's poorest city.

Police found 26-year-old Markice and Maurice Harper dead in Camden just after 7:30 a.m. Friday.

Authorities believe the brothers were shot hours before a passing motorist called 911.

No arrests have been made.

Crime rates in the city of 77,000 across the river from Philadelphia are among the highest in the country.
