An experienced climber died Sunday when she fell about 30 feet off a climbing wall at a Grapevine, Texas, climbing gym. Police say the death was an unfortunate accident.

According to this story from WFAA in Dallas/Fort Worth, police say "52-year old Susan Mallioux likely forgot to clip herself into the safety rope system provided by [Summit Climbing]."

She was climbing with her boyfriend and his son. Once Mailloux reached the top of the wall, about 25 to 30 feet up, police say Mailloux let go, as if she thought she was tied in.

More from WFAA: "Once she got to the top of that road ladder she simply released as if she was attached to it and then she fell to the ground," said Sgt. Robert Eberling with the Grapevine Police Department.

The gym requires climbers to sign a waiver warning against all types of possible injury or death, including "freakish accidents which cannot be forseen." Police say Mailloux failed to clip into what's called an auto-belay, an automatic harness system that lowers a falling climber, slowly, to the ground.

According to another Summit climber, Ben Mann, who did not know Mailloux, "All of the rock walls are lined with ropes and about every five to ten feet there's a sign that says don't forget to clip in, or make sure you're clipped in."

Summit climbing was closed Monday and will be closed again today out of respect for Mailloux and her family.

Just as skydivers are told to actually look at their ripcord before pulling and scuba divers are told to check that their air is actually turned on before getting in the water, rock climbers should check to see that their belay clip is actually clipped.
I just left my favorite new hobby, wall climbing at ClimbNashville. Since a hip injury is keeping me from running I have discovered that climbing is a 'better' substitute. I can not tell enough people enough good things about climbing! It is as safe or as risky as running. Awareness of personal safety is paramount in any endeavor, be it recreational or otherwise. I am very sorry that this accident happened. We must focus on the 'take home' lesson and keep on climbing!

A person fell to hear death on a climbing wall ???? It is time to outlaw all climbing walls. After all, we must be SAFE above anything else (but I do feel VERY sorry for her loved ones). I guess we will outlaw mountains also because we have several deaths per year her in our state due to climbing deaths. America has lost it's mind between 'safe' and 'diversity'.
TOM, who is trying to outlaw climbing walls due to this 'tragic ACCIDENT' article...besides good ole facetious (and dramatic) you? Looks like you have a bone to pick elsewhere.
Yes, the nanny state of CA will surely take action, but my better idea is to virtually eliminate highway fatalities by making a maximum speed limit of 5mph.
