Joanna Zielinski, 62, (left) was arrested on Thursday in Naples and charged with misdemeanor domestic battery for allegedly stabbing her sister Laura (right) repeatedly with an EpiPen
Officers with the Naples Police Department responded to the Zielinksi home at around 10.30pm after someone called 911 and then hung up,
Laura told the officers that she had woken up to find Joanna attacking her with the EpiPen prescribed to the latter sister to counter severe allergic reactions.
When interviewed by the officers, Joanna allegedly said: ‘I’m allergic to drunks, so I injected her with the EpiPen so she wouldn’t be drunk anymore. What’s the big deal?’
Using an EpiPen, which injects the drug epinephrine, on someone who is not having a severe allergic reaction can cause a dangerous spike in blood pressure.
First responders evaluated Laura and found that no medication was injected into her due to the way Joanna was holding the EpiPen during the attack.
However Laura was left with a large welt on her thigh where her sister stabbed her.
Joanna was booked into Collier County jail pending an arraignment on March 1, records showed.
Laura allegedly told investigators that she had been hurt by her sister on multiple occasions in the past.
