Kiesha Summerhill and her 19-year-old boyfriend, Arion Cruthird, face murder charges in the Jan. 7 death of Alice Wright. The charges were announced by Brownsburg Police Sgt. April Hyde during a news conference, which was live-streamed by WXIN.

Summerhill had previously cared for Wright’s husband, Kerney.

Police say the pair broke into the senior couple's home and robbed the Wrights. Alice Wright's daughter alerted police after she found her mother in her bedroom with an apparent gunshot wound.

Kerney Wright, who uses a wheelchair, was found in another room in the home. He was treated at a hospital for health issues unrelated to the case, police said.

Investigators believe Alice Wright was likely dead for 12 hours before she was found. The autopsy report ruled the manner of death as homicide and the cause of death as multiple traumas “that complicated her hypertensive cardiovascular disease,” the Indy Star reported.

Hyde said investigators have made steady progress in the case over the last five days, but said there remain plenty of questions that need answers.

“It’s been rapidly evolving, but it’s also been very cumbersome and tiring for the investigators,” Hyde said, “and I can’t even imagine what the family is going through.”

Hyde also alerted residents of Brownsburg to take proper precautions to protect themselves from crime.

"In this day and age, you need to stay aware of what's going on around you, you do need to protect yourself," Hyde said. "There's no leaving your doors unlocked to your residence anymore. There's no leaving your cars unlocked. These crimes are happening, and they're happening more frequently in our community, unfortunately."
