MICHIGAN CITY, Indiana (AP/WGN) — An Indiana man convicted in the 1997 killings of his brother and three other people is set to receive a lethal injection by early Wednesday in the state’s first execution in 15 years, and his wife spoke with WGN News just hours before his scheduled execution. Joseph Corcoran, 49, has been on death row in Indiana since 1999, the year he was convicted in the shootings of his brother, 30-year-old James Corcoran, his sister’s fiancé, 32-year-old Robert Scott Turner, and two other men: Timothy G. Bricker, 30, and Douglas A. Stillwell, 30. Barring last-minute court action or intervention by Gov. Eric Holcomb, Joseph is set to be put to death before sunrise Wednesday at the Indiana State Prison in Michigan City, according to state officials. Last summer, the governor announced the resumption of state executions after a yearslong hiatus marked by a scarcity of lethal injection drugs nationwide. The Indiana Department of Correction said Joseph requested Ben and Jerry's ice cream as his last meal. The state has provided few details about the process, including a specific execution time. No media witnesses will be permitted under state law. Indiana prison officials provided photos of the execution chamber in advance, showing a space that looks like a sparse operating room with a gurney, bright fluorescent lighting, a floor drain and interior windows to an adjacent viewing room.

"I have been in contact with one sister and she was here earlier and it's just very hard for the family," Tahina said. She and Joseph have known each other since junior high school. Tahina came to the Indiana State Prison in Michigan City to say goodbye. "We are best friends. We have a very loving relationship, friendship, marriage, just like any other couple," Tahina said. Joseph’s attorneys have fought the death penalty sentence for years, arguing that Joseph is severely mentally ill, which affects his ability to understand and make decisions. Joseph exhausted his federal appeals in 2016. Earlier this month, his attorneys asked the Indiana Supreme Court to stop his execution but the request was denied. However, attorneys say since the justices were split 3-2 that signals there’s a chance. “Given that it is a close case, it shouldn’t be rushed through,” said defense attorney Larry Komp. “He’s so extremely mentally ill. We think he’s irrational. We’ve never had a fair process.” In recent days, Tahina, members of the faith community and opponents of the death penalty have reached out to Indiana Gov. Eric Holcomb's office, asking him to stop the execution. "I’ve been very transparent about my position on capital punishment as a form of justice, so that hasn’t changed. I have supported it publicly, said so when I was running for the office, said that I would if called upon, carry out my duty," Holcomb said. "We've seen the number of executions and new death sentences drop dramatically over these years. So it's an unusual decision to move forward," added Robin Maher, executive director of the Death Penalty Information Center. Those questioning the execution point to Joseph's mental health, claiming psychologists have diagnosed him with paranoid schizophrenia. Despite several appeals, federal and state courts have upheld the execution. "Well, one thing that I found very striking about Mr. Corcoran's execution is the fact that the prosecutor, who initially sought his death sentence, has now said he would not make the same decision today," Maher said. Indiana State Rep. Bob Morris (R-District 84) filed a bill last week that would repeal the death penalty in Indiana. He also asked Holcomb to delay Joseph's execution so the legislation can be considered.

According to court records, before Joseph fatally shot the four victims in July 1997, he was under stress because the forthcoming marriage of his sister to Turner would necessitate moving out of the Fort Wayne, Indiana, home he shared with his brother and sister. He awoke to hear his brother and others downstairs talking about him, loaded his rifle and then shot all four men, records show. While jailed, Joseph reportedly bragged about fatally shooting his parents in 1992 in northern Indiana’s Steuben County. He was charged in their killings but acquitted. If he is put to death as scheduled by early Wednesday, it will be the state’s first execution since 2009. In that time, 13 executions were carried out in Indiana but those were initiated and performed by federal officials in 2020 and 2021 at a federal prison in Terre Haute. Indiana’s last state execution was in 2009 when Matthew Wrinkles was put to death for killing his wife, her brother and sister-in-law in 1994. State officials have said they couldn’t continue executions because a combination of drugs used in lethal injections had become unavailable. For years, there has been a shortage across the country because pharmaceutical companies have refused to sell their products for that purpose. That’s pushed states, including Indiana, to turn to compounding pharmacies, which manufacture drugs specifically for a client. Some use more accessible drugs such as the sedatives pentobarbital or midazolam, both of which, critics say, can cause intense pain. Last week, Joseph’s attorneys filed a petition in U.S. District Court of Northern Indiana asking the court to stop the execution and hold a hearing to decide if it would be unconstitutional because Joseph has a serious mental illness. They cited “severe and longstanding paranoid schizophrenia.” But the court rejected the bid to intervene on Friday, prompting attorneys to file an appeal with the U.S. Court of Appeals for the 7th Circuit. Multiple groups, including religious groups and disability rights advocates, have opposed the execution. Several activists were planning a vigil starting late Tuesday outside the prison, about 60 miles (90 kilometers) east of Chicago. In early December, Indiana Disability Rights asked the governor to commute Joseph’s sentence to life imprisonment without the possibility of parole. Holcomb recently said he would let the legal process “play out” in Joseph’s case before deciding whether to intervene. One of Joseph’s sisters, Kelly Ernst, who lost both a brother and her fiancé in the 1997 shootings, said she believes the death penalty should be abolished and her brother’s execution won’t solve or change anything. She is not planning to be present for the execution. Ernst said she had been out of contact with her brother for 10 years until recently. “I’m at a loss for words. I’m just really upset that they’re doing it close to Christmas,” she said. “My sister and I, our birthdays are in December. I mean, it just feels like it’s going to ruin Christmas for the rest of our lives. That’s just what it feels like.”
