LAKEWOOD, Colo. -- About a hundred neighbors packed the Green Mountain United Methodist Church Thursday night to meet with investigators about growing fire concerns.
West Metro Fire said since November 2016, there have been seven suspicious fires on Green Mountain.
"One is too many, let alone seven," said homeowner Diane Rhodus.
The largest one, which burned 300 acres in November, was dangerously close to Rhodus' house.
"When I came home there was this big ball of fire here and it was pretty scary," she said.
Last month, two more fires were set ablaze hours apart. The first fire sparked at 1:30 a.m. and the second shortly after 6 a.m.
"Happened at night, it's really hard for us to find witnesses," said Bruce Kral, the West Metro Fire Marshal.
Kral said they think one person is behind it, but have no physical proof which is why they're not ruling out other possibilities.
West Metro Fire has also created the Green Mountain Task Force to get help from the ATF and other law enforcement agencies.
"We're not taking anything for granted," said Kral.
All of the uncertainty has brought neighbors together in hopes of putting an end to it before the thick of fire season.
"It does make you real nervous," said Rhodus.
"The growth in the spring occurs, the drying out in the summer -- there is a chance for a more volatile type of fire," said Kral.
Rhodus said the neighborhood is looking to mount long range cameras outside homes and officials are asking the city to mow overgrown brush.
"This could definitely start on fire and come all the way through to our houses," explained Rhodus while showing the overgrown brush to Denver7 in Mountainside Park.
Homeowners are also doing their own mitigation efforts.
"Something's wrong and we have got to figure it out," said Rhodus.
