A 32-year-old Willmar man is being held in the Kandiyohi County Jail on assault charges after allegedly brutally beating the mother of his child. 

Efrain B. Guerrero Jr. is accused of repeatedly punching and using the handle of a kitchen knife to assault his girlfriend, who, according to a criminal complaint, was left with black eyes, missing teeth, bruising around her head and indents and puncture wounds consistent with being beaten with a knife handle. 

Police didn't learn of the attack until Jan. 6, four days after the incident occurred. 

The criminal complaint says that Guerrero became angry with the victim when he found out that she was sending Snapchats to another man. Guerrero is accused of threatening the other man, replying to him: "See if you like her without her teeth," the complaint says. 

The victim told police that Guerrero punched her in the face three or four times while she was holding their 1 1/2-year-old child. The child was able to run away from the violence, which continued with Guerrero punching the victim for another 90 minutes to two hours. 

The complaint says Guerrero stopped punching and began using the handle of a "cleaver-type chef knife" to hit the woman 15-20 times on the "front, side, back, and top of her head." 

Once Guerrero stopped assaulting her, she was able to get off the floor and push him to the ground. But her attempt to escape was thwarted by dizziness and an inability to see due to the amount of blood in her eyes. Guerrero caught her and dragged her by the hair, then kicked and stomped on her back, according to the charging document. 

Guerrero made the woman take a shower, during which he invited another woman to the residence to help clean her up. The woman recommended she go to the emergency room but Guerrero wouldn't allow her to leave. 

The next day, once swelling in the victim's eyes decreased, Guerrero allowed her to go. 

On Jan. 6, police were alerted to the assault by the victim's mother. 

Guerrero was arrested Jan. 8 but denied assaulting the woman, instead blamed her injuries on the friend who he invited over to help clean her up, claiming they had gotten into a fight over jealousy of him. 

Guerrero has been charged with first-degree assault causing great bodily harm, second-degree assault, domestic assault, and violation of a no-contact order, all of which are felonies. 

He also has two prior domestic violence-related convictions dating back to 2011.
