On May 25, 2017, officers went to his home to do a welfare check after a neighbor called 911 and told them about a man named 'Brandon' who appeared to be having a mental breakdown, was standing naked in a hallway, and was threatening to hurt himself

The officers found Trammell standing in his apartment's shower, looking blankly at them and failing to respond to their commands to show his hands and step out.

The officers, Michael Rohleder and Anthony Munoz, tell Trammell that they are about to tase him.

'Brandon, I need you to come on out,' one officer said, warning him that he's 'going to get tased' if he doesn't.

The officers incorrectly referred to Trammell as 'Brandon' because that's the name the caller gave them.

After an officer used his stun gun for the first time, Trammell immediately laid down on his back in the tub as he screamed in agony.

Thirty minutes elapse between the time Trammell is first tased and when he loses consciousness

Officers from a neighboring police department and Milwaukee paramedics eventually arrived to help.

At one point, Trammell stopped breathing and he was taken to a hospital, where he was pronounced dead.

Trammell's family told police he had a history of 'oppositional defiant disorder' and that he was possibly schizophrenic and bipolar

In total, he was tased 18 times.

Less than an hour after he was tased, Trammell was pronounced dead upon arrival in the emergency room.

The officers won't face charges because prosecutors found no link between his death and their actions.

Milwaukee County District Attorney John Chisholm said in an April 19 letter that officers 'did not violate the law' when they responded to a medical emergency last year 'under complex circumstances.'

An autopsy says the cause of death was 'excited delirium' and the manner 'undetermined.'

Trammell's family reacted angrily to Chisholm's decision.

'I think those people should resign. The D.A. and the chief of that police department,' Trammell's father, Larry Trammell, told the Journal Sentinel.

Trammell's family told police he had a history of 'oppositional defiant disorder' and that he was possibly schizophrenic and bipolar, although they weren't sure and didn't know what medication he was taking, according to the medical examiner's report.

His family also said Trammell had another encounter with police two years ago because he was running outside naked and the officers used a stun gun then, too.

The medical examiner's report also said that preliminary information from the doctor who first saw Trammell at the hospital last year indicated he had ingested some household cleaner.
