Two convicted sex offenders will move to Wausau next month, according to a notification from the Wausau Police Department.

Jack Martinsen, 52, has been on extended supervision since 2015 and living in Merrill, but will move to Wausau May 1.

Nicholas Kavajecz, 38, has reached his mandatory release date from prison and on May 19 will be released back into Marathon County, where he was convicted.

Martinsen was convicted in 1986 and in 1989 of sexual assault of a child. Earlier this month, Martinsen was discharged from his commitment as a sexually violent person. Though his Dept. of Corrections supervision has expired, he must continue to be monitored by GPS and must abide by sex offender registry requirements.

Kavajecz was convicted in September 2010 of possessing child pornography. After his release from prison, he will be monitored by sex offender agent specialists and will be subject to GPS monitoring. He will be living in the 6700 block of Calvin Drive in Wausau and will be on a highly restricted schedule with time out in the community for work and treatment, police said.

The ongoing status of both men will be updated and available online through the Wisconsin Sex Offender Registry at
