BANGOR, Maine — At the beginning of next month, Somerset County will become the first county in Maine to use electronic monitoring devices — or ankle bracelets — to track the movements of high-risk domestic violence suspects.

The devices are designed to alert authorities when people charged with domestic violence crimes go places they are not supposed to be, such as the homes, schools and workplaces of their victims.

Somerset County District Attorney Maeghan Maloney said Thursday that the $14,000 in seed money for the program came from Ralph and Linda Bagley of Harmony, who raised it during a June walk in memory of their daughter Amy Lake and grandchildren Monica and Coty Lake.

Maloney said that the Bagleys asked that she and Somerset County Sheriff Dale Lancaster, who also is part of a long-standing group working to end domestic assault and sexual violence, use the funds for monitoring devices.

“It was their passion that created this program,” Maloney said of the Bagleys. “They’ve wanted to have electronic monitoring, they’ve been wanting this to happen, for a long time,” she said.

In June of 2010, Amy Lake and her children were shot to death by Amy Lake’s estranged husband, Steven Lake, who then turned the gun on himself.

In the year that Amy Lake’s protection from abuse order was active against Steven, he violated that order at least five times but spent fewer than two days in jail for those violations, a report about the incident noted. He also stalked her on Facebook, it said.

The fifth time he defied the protection order, he killed his family and then himself at the house at 173 Shore Road in Dexter where Amy and her children were living.

Maloney said the Lakes would still be alive had a monitoring device been available.

According to Maloney, the monitoring program will involve setting “inclusionary” and “exclusionary” zones.

When the offender enters an exclusionary zone, Somerset County emergency dispatchers will be notified. Law enforcement officers then will be deployed and victims warned, she said.

The monitoring devices also track whether an offender is breaking curfew, she said.

“It gives us another tool,” she said. “It’s the best chance we have for victim safety that we can think of right now.”

To make the program self-sustaining, the $7-a-day fee the vendor is charging for each ankle bracelet will be made a condition of release in lieu of cash bail, Maloney said.

Ankle bracelets might not be the best alternative for all high-risk offenders, Maloney said. In some cases, a high cash bail — or no bail at all — might be more appropriate, she said. Whether the monitoring devices will be used will be decided on a case-by-case basis.

Maloney said offenders will be assessed on two point-based scales, one of which assesses offenders and gauges their likelihood of reoffending and another that looks at cases from the victim’s viewpoint.
