KALAMAZOO, MI -- The trial for Jason Dalton, the man charged with the 2016 Kalamazoo mass shooting that killed six people, will be delayed again after a Michigan Supreme Court ruling.

In the ruling dated Wednesday, March 21, the Supreme Court remanded an appeal by Dalton involving statements he made to police back to the Michigan Court of Appeals.

Originally, the Court of Appeals said it wouldn't hear the appeal. Now, with Wednesday's ruling, it has to hear it. The appeals court will likely review pleadings by the prosecution and defense and listen to oral arguments from each side before issuing an opinion, Kalamazoo County Chief Assistant Prosecutor Scott Brower.

The Court of Appeals will decide whether statements Dalton made to investigators the day following the Feb. 20, 2016, shooting will be allowed as evidence in his trial, and then a court date will be set in Kalamazoo County. "This will result in further delay" of the trial, Brower said Wednesday.

Kalamazoo County Circuit Court Judge Alexander C. Lipsey on May 24 denied a defense motion to suppress some of Dalton's statements to police following a shooting during which Dalton allegedly killed six people and seriously injured two others. Lipsey stayed proceedings at the request of Dalton's attorney, Eusebio Solis, until the appeal process is finished.

Defense attorneys argue Lipsey erred in denying the motion to suppress statements he made to a Michigan State Police detective at the Kalamazoo County Jail, and that Dalton's constitutional rights were violated.

Dalton, an Uber driver, is accused of going on a shooting rampage the night of Feb. 20, 2016 at three locations in Kalamazoo County, killing Judy Brown, Barbara Hawthorne, Mary Jo Nye, Mary Lou Nye, Rich Smith and Tyler Smith, and injuring Tiana Carruthers and Abigail Kopf.

Dalton, 47, of Cooper Township, faces six counts of murder, two counts of assault with intent to commit murder and eight felony firearm counts. He was found competent to stand trial in April 2016 and in May 2016 was ordered to stand trial. Solis has filed a notice of intent to use an insanity defense.

Lipsey ruled April 20 that the entirety of an interview Dalton had with a Michigan State Police detective will be allowed at trial, but only portions of an interview he had in the early morning of Feb. 21, 2016 with Kalamazoo Department of Public Safety detectives will be allowed.

Solis argued at a hearing that detectives violated Dalton's constitutional rights in two separate interviews. He said Dalton told detectives 25 times he didn't want to speak.

Kalamazoo County Assistant Prosecutor Jeff Williams argued, meanwhile, that the goal of the KDPS interview wasn't to get evidence against Dalton, but rather to learn of the threat of public safety, which is an exception to the Miranda rule.

Williams also argued Dalton initially invoked his Fifth Amendment rights when being interviewed by State Police Detective Kyle Gorham, but later initiated a conversation about the investigation and waived his rights.

Police reports about the interviews were included in information released by police in 2016 as part of Freedom of Information Act requests.

According to the reports, Dalton told KDPS Detective Bill Moorian, who interviewed him with KDPS Detective Cory Ghiringhelli, that his explanation for the shootings would blow their minds.

"Dalton then explains how when he opens up the Uber taxi app a symbol appeared and he recognized that symbol as the Eastern Star symbol," Moorian wrote. "Dalton acknowledged that he recognized the Uber symbol as being that of the Eastern Star and a devil head popped up on his screen and when he pressed the button on the app, that is when all the problems started."

Gorham wrote in his report that Dalton said he hadn't been sleeping well because the Uber app wouldn't let him "shut down."

According to Gorham's report, Dalton also talked about how he received a message on his phone to "plug in an auxiliary cable into his car, along with the power source for his phone and a Bluetooth." On Feb. 20 he said he was asked to take an assignment from Uber and when he got into his car he began driving really fast, the report says, and "advised something had come into his car."

Dalton, the report says, claimed the Uber app communicated to him with "dings," with one meaning yes, and two meaning no. He also told the sergeant things "began to get really weird" and he "freaked out" after symbols popped up on his Uber app asking him to join, which he agreed to do.

Dalton told Gorham the Uber app on his iPhone was to blame, claiming the app took over his Chevrolet Equinox - and later his body - and said "things began to get really weird" in the hours before the shootings.

Dalton remains jailed without bond.
