KANSAS CITY, KAN. ? The ex-convict wanted in a shooting rampage that left five people dead earlier this week had at least 13 disciplinary violations in prison, and the head of the state parole board now says that paroling the man “obviously” looks like a mistake.

Darrell L. Stallings, 32, is charged with five counts of capital murder in one of the bloodiest days in memory in Kansas City, Kan. Police have arrested his alleged accomplice, Errik Harris, 26, who faces four counts of capital murder.

Stallings became one of the most-sought fugitives in the Kansas City area just 10 months after he was paroled from a second-degree murder sentence.

Police have said this week’s crime was tied to drug-dealing, while some victims’ family members believe the killings were about revenge.

Last time, the killings were about a botched drug deal. Authorities say two people were shot to death and two others wounded. Stallings began serving a sentence of 20 years to life in March 1989 after he was convicted of two counts each of second-degree murder and aggravated battery.

He was paroled Aug. 28, 2001, according to the state Department of Corrections. Parole board chairwoman Marilyn Scafe said Stallings was paroled in part because he was an accomplice in the earlier murders, and that the gunman was still serving a life sentence.

While in prison, Stallings was disciplined for offenses including being in a restricted area, fighting, and drug violations, according to Department of Corrections records.

His toughest prison discipline came in June 1997, when he received 32 days in segregation and lost 30 days of “good time” for fighting. “Good time” is time earned for good behavior.

The two drug-related infractions are from 1996 and 1997, and are labeled “use of stimulants, sedatives, unauthorized drugs, or narcotics, or the misuse, or hoarding of authorized prescribed medication.” Details of the infractions aren’t given.

However, after his 1997 drug infraction, Stallings had what appear to be minor infractions. His most recent was a $5 fine for an “unauthorized presence” in 1999 two years before he was released.

Violations before 1996 were not immediately available.

Stallings had some discipline problems when he was first locked up, Scafe said, “But as he matured, he sort of turned a corner in becoming active in programs and participating in pre-release sorts of things.”

He even had a sponsor, which not all inmates bother to do, she said.

“At the time that he came up for review, there were a lot of things in his favor,” she said. “It looked like he was doing fine.”

Scafe was sent to a halfway house when he was released, Scafe said. And since he was paroled, Stallings apparently had no major infractions, because his parole was not revoked, Scafe said.

Asked if paroling Stallings now looks like a mistake, Scafe said, “Obviously it does. But at the time we made our decision, we made it with good faith that this person could go out and make it.”
