COLORADO SPRINGS — Gun evidence links a Colorado parolee fatally shot in Texas with the death of Colorado’s correctional chief, investigators said Monday.

The El Paso County sheriff’s office said that ‘‘unique and often microscopic markings’’ found on shell casings in Texas and Colorado lead investigators to conclude that the gun Evan Ebel used to shoot at authorities in Texas was the same gun used to kill Tom Clements at his home last Tuesday.

It had been known that the casings found at both scenes were of the same caliber and brand but Monday’s announcement was the first time that Colorado investigators made a direct link between Clements’s death and Ebel.

What remained unknown though was why Clements was killed Tuesday night and whether Ebel acted alone.

‘‘There are no answers at this time surrounding motive, and gaining these answers could be a lengthy process for investigators,’’ sheriff’s spokesman Lieutenant Jeff Kramer said in a statement.

The announcement came after hundreds of people gathered for a memorial service to honor Clements.
