Stephen Dinnan's family's last moments were with the 35-year-old covered in bruises and unresponsive in a hospital bed.
At about 6:30 p.m. Tuesday, his family took him of life support at Castle Medical Center.
"She's very distraught. Obviously, she lost the love of her life," said defense attorney Bill Harrison.
On Wednesday, his girlfriend, Shardeah Serhant, and mother of two of his young children, lawyered up, disputing a new report by the medical examiner that her boyfriend showed no signs of being assaulted.
"We're very skeptical about the information that's been released so far," said her other attorney Roy Bell.
"I think it's kind of crazy because there are all kinds of bruises and marks on Stephen's body. He was battered about the throat, the arms and the back," said Harrison.
On Monday, police say they went to a home on Ala Koa Street in Waimanalo after the owner of a stolen truck said he traced his cell phone to the location.
Neighbors said they saw part of what happened.
They told KITV they saw Dinnan jump over a fence and put a child on a neighbor's back step.
They said police officers told him to stop, but instead, he jumped back over the fence and started running.
Officers said they found drugs and drug paraphernalia on Dinnan.
In a statement, Honolulu police say Dinnan "...fought off and resisted attempts to detain him."
Dinnan's sister told KITV her brother was just in the wrong place at the wrong time.
"This was a theft case at best and at this point we believe Stephen wasn't involved in anything," said Harrison.
His family said he was in Waimanalo to meet a friend.
Police said Dinnan had no prior criminal record.
The officer involved in the arrest has 26 years of service and is now on administrative leave -- which is standard procedure.
Serhant's attorneys said they're waiting for the full medical examiner's report to get a better picture of what happened.
