A jogger dubbed the 'mad pooper' after she was busted defecating on front lawns in a Colorado neighborhood is not at fault because she has a traumatic brain injury caused by gender reassignment surgery, according to her mysterious spokesman.

An unidentified man claiming to be 'a family representative' of the woman said the jogger wanted to apologize but added that she couldn't help it because she could no longer control her bowels.

The man refused to identify himself or the jogger in a series of since-removed YouTube videos he posted online, KRDO reports. He also declined to verify he was speaking on the jogger's behalf.

He claimed the woman's actions were no different to breastfeeding in public.

Police in Colorado Springs were on the lookout for the mad pooper after a family spotted the woman with her pants down outside their home two months ago.

Cathy Budde said her children were the ones to catch the jogger mid-squat and ran in screaming to tell her.

'They are like, "There's a lady taking a poop!" So I come outside, and I'm like ... "are you serious?"' Budde told KKTV.

'A"re you really taking a poop right here in front of my kids!?" She's like, "Yeah, sorry!"'

The jogger has defecated in the same spot on her running route every week for almost two months

Budde said she thought it was just a one time thing and the woman would have been too embarrassed to show her face again.

But she said the jogger has been back once a week to defecate, despite there being public restrooms in a nearby park.

The woman always has paper towels tucked away in her tights, according to the shocked family.

'I put a sign on the wall that's like "please, I'm begging you, please stop." ... She ran by it like 15 times yesterday and she still pooped,' Budde said.

Police urged Budde to take photos of the woman in a bid to track her down.

The jogger could face indecent exposure and public defecation charges if she is caught.
