DENVER (AP) -- Four wanted parole violators have now been rounded up as part of a renewed effort following murders allegedly committed by Evan Ebel.
At the end of March, the Department of Corrections reported 667 violators being sought out of 9,490 Colorado parolees.
According to KMGH-TV, about 30 of those absconders have alleged gang affiliations.
The roundup has renewed fervor after the March murder of corrections chief Tom Clements. Ebel set off a tamper alarm from his electronic monitoring anklet on March 14, about three days before he allegedly murdered a part-time pizza delivery man. Two days after that, Ebel allegedly rang the doorbell at Clements' home and shot him to death.
Ebel was later killed in a shootout in Texas.
