A tragic mass shooting is the focus of a miniseries project at Lifetime, which will involve the creative team behind "Moneyball" and "Mildred Pierce," according to The Hollywood Reporter’s The Live Feed blog.

The miniseries would be based on the 2009 book “Columbine” by Dave Cullen, which recounts the events of the 1999 school shooting in Colorado, in which 15 people died — including the two shooters, who were students at Columbine High School.

Tommy O’Haver of "An American Crime" would write and direct the project, while Michael DeLuca of "Moneyball" is in discussions to produce, along with Christine Vachon and Pam Koffler of "Mildred Pierce," the story says.
