Gary police looking for person of interest in grandfather's murder; considered 'unstable,' armed

GARY, Ind. (WLS) -- Gary police have released a photo of person of interest in the murder of a 79-year-old man.

Police said they were called to the 3200-block of West 21st Place in Gary on Wednesday night for a gunshot victim who was bleeding and unresponsive in the street. The man was pronounced dead at the scene.

The victim was identified as 79-year-old Cornelius Olive.

Family members say he was walking his granddaughter' dog when he was killed.

"It's sad he died doing something he did every day, which was walking my dog," said Kamarie Caldwell, granddaughter.

Caldwell was the one who found her grandfather, after hearing gunshots, in the street in a pool of blood.

"I'm a medical assistant, so my first thought was maybe I can save him," she said. "So, I went in the house and I grabbed a towel and I was telling the operating he was still breathing!"

Gary police named Tyree Gaines as a person of interest in the murder. They said he has emailed the city of Gary and other neighboring communities, and made threats over email. Police said they believe he is unstable, and is considered armed and dangerous.

Gaines is described as a 24-year-old Black male, 5 ft. 5 in. tall and 115 lbs. Police are urging him to turn himself in.

If you see Gaines or have information about his whereabouts, Gary police say you should not approach him and instead call 911.
