A "dead end" in north Tulsa is proving to be just that.
In the last eight years, the end of the road at 129th East Avenue and 46th Street North has resulted in six deaths.
The most recent one occurred Saturday . Tulsa Police Sergeant Chris Witt confirmed 56-year-old John Bowers died on impact from hitting boulders at the "T" intersection.
It's a deadly crash that infuriates Lori Gaches and Darrell Adams.
In 2009, Gaches lost her son Mark, just two days after his 23rd birthday. Mark and three friends, including Troy Adams, were out celebrating when they went down a road unknown to them.
The four people landed down in APAC rock quarry. Only one survived.
Ever since the triple-fatality, Gaches and Adams have fought for more signs, lights and warnings in the area. Gashes wrote senators, governors and the City of Tulsa. As deaths continue to increase, they still want more.
"I'm going to write the governors again," Gaches said. "I'm going to write the senators again. I'm on a mission. I'm not going to shut up."
Adams said the death of his only son devastated every aspect of his life.
"I try to find a light at the end of the tunnel, it just seems like it gets further and further away," Adams said.
APAC rock quarry has put up boulders over the years to make sure drivers don't go over the cliff into the quarry.
On Christmas Eve 2006, 23-year-old Buddy McCoy went through the "dead end" and down into the quarry. He was missing five days until workers found him.
After that APAC installed two boulders.
On Sept. 5, 2009, a Nissan Titan went into the rock quarry. Amanda Stone, Andrea Merriman, Troy Adams and Mark Gaches were inside. Stone was the only survivor.
APAC installed more boulders.
On Sept. 12, 2013, 55-year-old Timothy Baker died from the impact of hitting the boulders. Sgt. Witt said he wasn't wearing a seatbelt.
Tulsa Engineer Kurt Kraft said after this wreck, he installed a "double arrow" sign to warn drivers the road splits. Kraft also installed a street light.
Saturday, March 1, 2014, Bowers died from the impact of hitting two sets of boulders, one right after the other. His Dodge Dakota was wedged in-between the rocks. Sgt. Witt said there was no sign of alcohol and Bowers wore a seatbelt.
"Now I'm getting angry,” Gaches said. “It's past the point; my heart hurts so bad for those people. I know what they're going through. I know the heartache they feel everyday losing that family member. They shouldn't. It shouldn't happen again."
Kraft said he will drive the area this week and wait for a traffic report to see if any more changes can be made.
Sgt. Witt believes installing red and yellow flashing lights would warn drivers. There are even solar powered options.
As for Lori Gaches, she's raising Mark's 9-year-old son, Dallas, who has muscular dystrophy and doctors said might not live past 23 years old. The same age his dad died.
“Just one more time, I want to hear ‘I love you,’ one more time,” Gaches said.
