District Mayor Muriel Bowser announced Wednesday that rewards for tips about guns involved in violent crimes will now be worth as much as $10,000, Washington City Paper reported.

Tips that lead police to recovering illegal guns, which had previously earned $1,000, are now worth $2,500. And if the gun was used in a shooting, the tipster will earn $10,000, according to Washington City Paper. The District also offers $25,000 to people who give tips on homicides.

The mayor cited increasing violence in the District as the main reason for increasing the rewards. The murder rate in D.C. has increased by more than 30 percent over the past year, and crimes involving guns in D.C. have increased by 20 percent so far this year, according to data published this month. Murders have increased by 18 percent this year alone, WTOP reported last month.

The mayor’s announcement comes a day after police investigated three separate fatal shootings in the District.

Metropolitan Police Department Chief Cathy Lanier said her department was more than willing to increase the rewards for tips, according to Washington City Paper.

“We’ll step up to the plate,” Lanier said. “We’ll add to the money.”
