A love triangle unfolded last week in Missouri as a wife watched her lover, 36, shoot her husband, 44, to death by blasting him in the back near a park in St. Louis.
Erik Seitz was arrested on a first-degree murder charge after allegedly firing a gunshot at Dennis Bieg near River Des Peres Park in St. Louis last Tuesday.
The tragedy occurred shortly after 4.15pm on October 7th, at the intersection of River Des Peres Boulevard and Wanda Avenue in south St. Louis.
St. Louis police rushed to the scene, only to find the victim, Bieg, shot in the torso and lifeless. He was pronounced dead at a nearby hospital.
A woman who identified herself as Bieg’s wife witnessed the shooting. She told officers that she had been romantically involved with Seitz, KSDK reported.

The St. Louis Circuit Attorney’s Office issued charges of first-degree murder and armed criminal action against Seitz in connection to the fatal shooting of Bieg.
Among the witnesses was Seitz’s ex-girlfriend, who arrived at the scene after she received a message from Bieg.
Bieg urged her to come to the park in the text. When she rushed to the scene, she heard the gunshots, saw Seitz with his arm out, and Bieg bleeding, according to court documents obtained by KSDK.
The third witness, who was with Seitz’s ex-girlfriend, said he saw Bieg get shot in the back ‘as he was walking away and posing no threat.’
Despite multiple witnesses identifying Seitz as the shooter, he denied having shot Bieg during police questioning.
‘When confronted with witness accounts of what they had witnessed, (Seitz) stated those accounts were inaccurate, denied having shot the victim and claimed he did not even possess a gun,’ police said.
Seitz accused Bieg of hitting him with an unknown object, which caused him to black out until he woke up while being taken into custody.

Seitz wrote on Facebook that he broke up with someone a month before the shooting
The shooting death came a month after Seitz broke up with someone, his Facebook post shows.
The suspect wrote: ‘This is complicated. Did everything she ever say to me turn out to be a lie? Yes. Did she break my heart to a point I don’t even know if I can come back from? Yes.’
It’s not clear what exactly led up to the shooting or the relationship between Seitz, Bieg, and two witnesses they had been involved with.
Police said they focused much of their attention on a red work van labeled Bieg Plumbing Company. The van was tolled away after the shooting.
The next day, Bieg Plumbing said in a statement that Bieg had been killed in an ‘unexpected incident’ that was unrelated to his work with the company.

Alderman Tom Oldenburg said violent crimes have been unusual for the neighborhood where the shooting took place.
‘I have received several calls from residents that live in very close proximity to the incident and they are very concerned and rightfully so,’ he told KSDK.
‘This is alarming, particularly at the time of day it took place and in a fairly active park,’
‘Violent crimes and homicides are very unusual for this neighborhood,’ Oldenburg said, adding that he’s in touch with authorities.
A bicyclist who rides through the park every night told the outlet that he had to turn around after he saw crime scene tape.
‘Not happy about it. Too much of that is going on these days,’ he said. ‘I just got to make a detour.’
