Black Country Coroner Zafar Saddique today recorded a verdict of a suicide over the death of the popular teacher.
Ms Humpage taught English at South Wolverhampton and Bilston Academy, where she met her partner Joe Clarke. The inquest at Black Country Coroners Court heard Ms Humpage initially took a overdose in June after Mr Clarke broke up with her after two years together.
Katie was offered support by the mental health unit at Walsall Manor Hospital after but she declined the help, saying she did not want to die.
Mr Clarke told the inquest: "We went on holiday but I ended the relationship soon after we arrived back, as I could not see a future together."
He said Katie had told him via text message she overdosed due to the break-up but later tried to retract the statement.
He said had no reason to believe Katie would then go on to commit suicide. The inquest was told that by July she seemed to be getting over the break-up before taking another bad turn.
She was upset when she spoke to her mum on the phone on the day of death about the break-up and how she could see little point going on with her life.
Katie’s stepfather Lee Horney told the inquest he grew concerned when he called her but received no answer.
"I was worried so I went to her house," he said.
"I had my own key. Her house was in darkness. I eventually gained entry and went upstairs, which is where I found Katie lying on the bed.
"I called the ambulance and was about to perform CPR. But the paramedics arrived and she had already passed away."
