In India, one woman dies every hour because of dowry-related crimes, according to the National Crime Records Bureau.
The agency says 8,233 women were killed across India last year because of disputes over dowry payments given by the bride's family to the groom or his family at the time of marriage.
Each year, thousands of young Indian women are doused with gasoline and burned to death because the groom or his family felt the dowry was inadequate.
Indian law prohibits the giving or receiving of a dowry, but the centuries-old social custom persists. Kanjana Kumari, a women's rights activist, cites a culture of greed as the cause.
"Marriages have become commercialized," Kumari said. "It's like a business proposition where the groom and his family make exorbitant demands. And the wealthier the family, the more outrageous the demands."
