PORTLAND (AP) — Two crimefighting initiatives proposed by Kevin Mannix appeared headed for rejection by voters on Tuesday while a less costly legislative referral offered as an alternative looked like it would win approval.

Mannix was behind Measure 61, which would have required mandatory sentencing of up to three years for first-time offenders convicted of property or drug crimes.

He also offered a companion but unrelated proposal, Measure 62, which was nicknamed “CSI Oregon’’ because it would have carved out 15 percent of lottery revenue to increase funding for the Oregon State Police crime lab and prosecutors.

Both appeared headed for defeat with nearly half the vote counted Tuesday.

A legislative referral offered as an alternative to Measure 61 was being approved by voters late Tuesday.

Measure 57 increases prison terms for repeat offenders convicted of nonviolent property or drug crimes. But it offers expanded treatment programs to prevent inmates from going back to their old habits.

The referral had the support of a coalition that included most district attorneys in the state, along with police chiefs, sheriffs, teachers, nurses and unions.

“It’s great that voters come together to support the broad-based coalition that supported Measure 57,’’ said Defend Oregon campaign spokesman Matt Blevins.

Supporters said the Mannix proposal not only lacked a drug treatment program, the cost would have easily exceeded $1 billion over the next five years, including the cost of building new prisons to hold all the inmates.

A fiscal analysis by the Legislature showed its Measure 57 would cost about $150 million less per year than Mannix’s Measure 61.

Democratic state Sen. Floyd Prozanski, one of the prosecutors who backed Measure 57, said inmate screening shows that drug or alcohol addiction is a problem for more than four out of every five people sent to prison.

He said treatment programs help reduce the number of repeat offenders, and there is widespread support for them among prosecutors, police and prison managers.

The other Mannix proposal, Measure 62, was nicknamed “CSI Oregon’’ because it would have amended the state constitution to boost funding for the Oregon State Police crime lab and prosecutors around the state.

But opponents said the schools would have lost a big chunk of their lottery support — about $100 million a year — by devoting 15 percent to the crime lab and district attorneys.
