WAUSAU — A citizen tip led to the arrest of a potential suspect in at least one of two Wausau armed robberies.

After surveillance photos were released on Tuesday, police identified Curtis Langlois 37, and his girlfriend, Holly Antijunti, 27, outside of WalMart in Rib Mountain, according to a news release. Police said a distinguishing skin discoloration spot was visible when viewing the Fast Break Mobil robbery surveillance video and helped lead to Langlois’s identification.

Both Family Video and Fast Break Mobil were robbed at gunpoint within the past week in Wausau.

Langlois had a significant amount of money when he was arrested and is on federal parole for robbery, police said. Antijunti was arrested on charges of obstruction after she allegedly provided misleading information to investigators.

Both Langlois and Antijunti were taken to the Marathon County Jail.

A search of the Wausau apartment shared by Antijunti and Langlois found additional clothing linking Langlois to the Fast Break Mobil robbery police said. The investigation continues into the connection with the Family Video robbery.

Anyone with information about these robberies is asked contact the Wausau Police Department, Detective Jeff Strobach at 715-261-7815.
