Unsolved murder still haunts grieving mother

TUCSON, AZ (Tucson News Now) - A bitter anniversary is quickly approaching for friends and family of Kyle Riley.

The 27-year-old man was killed Jan. 30, 2013 inside a home he shared with two people in the 4800 block of South Lantana Place.

The owner of the home, who was also one of Riley's roommates at the time, has since sold the property to another family, and hasn't been exactly forthcoming with information.

The third roommate who lived in the home remains unaccounted for to this day.

Investigators are reluctant to name that person publicly, but said he's definitely on their radar and is wanted by the US Marshals Service and the Tucson Police Department for a series of unrelated crimes.

But none more serious than what happened to Riley.

Riley had just moved from Sierra Vista, where he lived with his mother, to stay with a friend on Tucson's southeast side near South Kolb and East Irvington roads.

It's unclear if the owner of the home actually witnessed the shooting.

But he did call 911 at 8:54 a.m.

Riley was pronounced dead seven minutes later.

"I know there were two people in that home the time my son was killed," Mary Riley said. "One being the homeowner and the other being the other person."

Mary Riley said that third person reportedly fled the state and possibly moved to Mexico.

"I haven't heard anything more," she said.

On multiple occasions, she's driven from Sierra Vista to Tucson's southeast side to paper neighborhoods with reward posters about her son's case.

"Went door to door," she said, "to hundreds of houses."

She'll be doing the same this coming Saturday on the third anniversary of her son's death.

"I come several times a year and it never gets easier," Mary Riley said, shaking her head. "I just want to know what happened to my son. I have to know."

If you have any information about the murder of Kyle Riley call 911 or 88-CRIME.

A reward up to $2,500 will go to the person whose tip leads to an arrest and indictment in this unsolved case.
