CAPTURED: Assault suspect accused of viciously attacking new girlfriend arrested and booked into Yakima County Jail

David Wacenske, Jr. was arrested and booked into the Yakima County Jail on Sunday night, for charges of 2nd Degree Assault and Unlawful Imprisonment.

He's being held on $50,000 bail.

A mother tells Yakima County Sheriff’s detectives that she heard her daughter scream from outside their home, when she opened the front door, her daughter was grasping to a handrail as her brand new boyfriend was pulling on her with both hands.

Detectives say the victim was trying to escape a violent attack from David Wacenske, Jr. in January.

He's wanted for Unlawful Imprisonment and 2nd Degree Assault.

Detectives say the two had only been dating for a couple of weeks, when Wacenske, Jr. started asking the victim questions about old relationships, while the two were sitting in his car outside her home.

Detectives say Wacenske, Jr. got angry and violently attacked her -- choking her and hitting her in the head with his hands, then pulling a gun from his center console and hitting her with it, as well, before putting the gun in her mouth and then to his head and saying, ‘I'm either going to kill you, or myself tonight.’ The victim was able to escape from the car and yell for her mom who called 911, as Wacenske, Jr. took off in his car. Detectives do not have a description of the vehicle.

Wacenske, Jr. is 22 years old, 5’8” and weighs 145 pounds.
