Psychopath Hits Family With a Truck but Doesn’t Stop There

A story coming out of Montana sees a psychopath man who sped up in his truck to hit a family as they were minding their business strolling down in a tourist town lining Glacier National Park but doesn’t stop there.

After hitting the family, the man got out and equipped himself with a shotgun, injuring a young child who was in their mom’s arms and killing one man before the mother’s sister-in-law figured out how to stop the aggressor in his tracks after he ran out of ammo.

The incident happened on the Blackfeet Indian Reservation in northwestern Montana where David Siau, 39, was born in Syracuse, New York, and Siau’s 18-month-old daughter, McKenzie. The psychopath who decided to change the family’s lives forever was Derick Madden, 37, who had mental health issues and was also in a relationship in the past with Christina Siau, who eventually put an end to his killing spree, according to the Glacier County Sheriff’s Office.

Derick slammed his Toyota onto the sidewalk and into the Siau family at high speeds right before 9:00 p.m. Sunday as they were strolling in the humble community. The vehicle hit a few of the family members before crashing into a tree.

That’s when Derick got out of his truck and shot David Siau with his shotgun, killing him, and mortally injuring little McKenzie. The little kid was being held by her mom, Christy Siau, who attempted to run away, but was also shot in the process.

At that point, the ruckus suddenly stopped as Derick ran out of ammo. However, he wasn’t done, he pulled out a knife and began trying to slash at his sister-in-law, Christina Siau, 30. Be that as it may, the lady didn’t go down without a fight and in the end, she ended up lethally injuring Derick.

Authorities have yet to reveal how Derick was killed, but the threat was stopped.

Two other children with the family took off running when things started to hit the fan, and they were not harmed at all. McKenzie Siau was pronounced dead at the Indian Health Service emergency clinic in Browning. Christy and Christina Siau experienced critical wounds and were airlifted to another hospital with a more elevated level of care.

Spectators in the space saw the assault and quickly phoned authorities. Captain Tom Seifert with the Glacier County Sheriff’s Office said that police arrived at the scene in practically no time, yet the assault was at that point finished.

This is why it’s so important for you to stay armed to protect yourself, loved ones, and those around you. Police can arrive very fast in 1-2 minutes, but things like this happen in mere seconds.

Authorities depicted this incident as an “isolated…incident with a clear nexus between the victims and Madden” and said that the examination was in progress. It was not clear what provoked Sunday’s assault past the earlier relationship between Christina Siau and Derick.

A colleague of David Saiu had nothing but good things to say about him. “They just loved to do activities with them outdoors, even just fun simple things, like weekend and day trips,” said Peter Depuy.

Christy Siau was a previous clerk for the American Baptist Churches of New York State, as per social media postings by the association, and was depicted as “a long time and beloved member”. The pair were also active in the First Baptist Church of Hoosick Falls, New York.
