Police: Murdered couple was dating; police seek weapon

Man previously questioned in double homicide in Berlin arrested, booked into jail

Berlin police have arrested Nicholas Tunistra in connection with the shooting deaths of Melissa Tunistra and Justin Daniels on Saturday.

Nicholas Tunistra is being held in the Green Lake County Jail on two counts of first-degree homicide. Police said witness statements led to the arrest.

Tunistra was questioned Sunday morning just hours after the two were found dead. He was released that night, but remained a person of interest.

Police said Tunistra was at the sheriff’s office when he was arrested but he wasn’t there for questioning or to turn himself in.

Police have described the deaths of Melissa Tuinstra and Justin Daniels as a double homicide. They were found slain late Saturday. The crime resulted in an Amber Alert for Tuinstra’s 8-year-old daughter who was found safe Sunday with relatives in a nearby community.

Police said court records show the Tuinstras had recently filed for divorce, and the two victims had been dating.

Berlin police said they’re asking the public’s help in looking for a handgun that they believe was the weapon used in the crime. Anyone who finds a handgun is asked to not touch it and contact Berlin police.

Police said there are more interviews to conduct and evidence to process in the case.
