KANSAS CITY, Mo. -- Michael Blackwell's death is a big, painful mystery to his family.

Tanya Johnson told FOX 4's Robert Townsend she can't believe that her fiancé and companion of five years died in such a horrible way.

Tanya said around 7:30 p.m. Saturday, Michael went to visit a longtime friend who was dying of cancer. Sadly, after three days, 60-year-old Blackwell never returned home.

"I was terribly devastated, and so was the family. We all knew that something terrible has happened."

A day after the family filed a missing person's report, police said construction workers spotted the mangled SUV Michael was driving under the 71-Highway bridge Monday morning.

Right now, neither police nor Michael's family know what caused the Army veteran, father, and grandfather to hit a barrier and fall over the bridge to his death.

"I couldn't sleep. I just felt it in my heart that something was wrong because he don't do that. He don't put me through that. He knows what I've been through in the past and he made sure that I don't go through that," Tanya said through tears.

Tanya said Michael had a huge heart and was the glue of their family.

"I knew that something was wrong, you know, and I'm pretty much lost without him because I have to re-adjust my life," fiancée Tanya Johnson. "I got to look at his clothes, and watch his brother grieve. Everyone's grieving. My kids are grieving. He's got one daughter, she can't be here because she's a mess."

Michael served 12 years in the Army. He had a daughter and a two-year-old grandson. He was also a caregiver for his elderly brother.

An autopsy will determine exactly how he died.
