The city of Los Angeles is now offering $75,000 for information leading to a conviction in the case, adding to USC's $125,000 reward.
The 23-year-old engineering students were sitting in a car in the West Adams District last week when they were shot and killed on April 11. The motive remains unclear, but police say it may have been a bungled carjacking.
Anyone with information is urged to call LAPD at (877) LAPD-24-7.
