A mixed martial arts fighter accused of beating his girlfriend inside her Las Vegas home told a California judge on Tuesday he will not contest his transfer back to Nevada.
Jonathan Koppenhaver, 32, also known as "War Machine," appeared in a Ventura County courtroom after his arrest on Aug. 15 in Simi Valley, CA.
Authorities in Las Vegas named him as a suspect in the reported assault on his girlfriend, Christine Mackinday, and her male friend on Aug. 8. A warrant was issued for Koppenhaver, who fled law enforcement in Southern Nevada.
Ventura County Sheriff's Capt. Don Aguilar said Koppenhaver will be transferred to Las Vegas but no date was specified.
On Monday, Las Vegas Metro police documents were released describing injuries from the assault in which Koppenhaver was named as the suspect.
In the documents, police stated Koppenhaver's girlfriend of 15 months, Mackinday, was admitted to a local hospital with apparent injuries to her face. She told police Koppenhaver entered her home earlier that morning and first attacked a male friend who was sleeping in her bed before he turned his attention to her.
According to the report, Koppenhaver accused his girlfriend, also known as Christy Mack, of cheating on him.
As described by Mackinday and her friend, the report states Koppenhaver first punched the male victim about 15 times in the face before putting him in a chokehold. Koppenhaver let the male victim leave but threatened to have his friends kill him if he told police.
Mackinday told police she called 911 but left the line open and hid the call from Koppenhaver.
Police said Koppenhaver then began punching Mackinday in the face. The report states she was forced to strip naked and go into the shower where her boyfriend yelled at her.
Mackinday told police Koppenhaver went through her phone and struck her every time he saw something on her social media accounts he didn't like. The report also stated Mackinday was kicked in the ribs while she was on the ground.
The report also described Koppenhaver's unsuccessful attempt to rape Mackinday.
Mackinday told police Koppenhaver retrieved a dull kitchen knife and held it to her head. She stated her opportunity to escape her home came when Koppenhaver went back to the kitchen to get a sharper knife to "finish the job."
She escaped to a neighbor's home where police were called.
In the report, Mackinday described her relationship with Koppenhaver as "on-again, off-again." She also said her relationship with the male victim was "non-sexual" but admitted she's had sex with him in the past.
Koppenhaver's charges include battery with substantial bodily harm, strangulation, two counts of domestic violence-related battery, domestic violence-related kidnapping, domestic violence-related open and gross lewdness and domestic-violence related attempted murder.
