Police in northern Colorado are investigating the possible relationship between shootings at a health care center and an elementary school over the weekend and are ruling out a connection to four other shootings that left two people dead, NBC News reported.
A spokesperson for the Northern Colorado Shooting Task Force said police have poured over leads and interviewed 10 people, but nothing is connecting the new shootings with the original four.
Someone fired shots on Sunday at the Banner Health Center building in Fort Collins, north of Denver, police said. No one was hurt. That same day, shots were fired at the Cottonwood Plains Elementary School in Fort Collins.
The FBI is offering a reward in the cases.
