COLORADO SPRINGS, Colo. -

For more than 20 years, Ken Sheehan has lived near the intersection of Marksheffel Blvd. and Bradley Rd.

He drives through the intersection all the time and says it's one of the most dangerous in the city.

"You'll come up on it expecting that the light is going to stay green then it will shift to red then it will shift to green again," Sheehan said. "You're not sure what's going to happen."

The most recent accident was last Friday afternoon -- and it was deadly.

Kimberly Mears and her 10-year-old son, Raley, were killed when their car broadsided a pickup.

The city says it's now investigating whether a power outage in the area may have caused the lights to malfunction just minutes before the deadly crash.

"We've not had an injury or fatality at that intersection before Friday's accident since 2007," Colorado Springs Transportation Manager Kathleen Krager said. "We feel the intersection is operating well, it's operated that way for a long time and I'm not planning on changing operations at this time."

Sheehan wants the city to take action now. 

"You can always replace vehicles but you can't replace people," he said.

The city says since it installed a traffic light at the intersection seven years ago it's only had two injury accidents including the deadly crash.
