CLARKSVILLE, Tenn. (WKRN) — There are seven Clarksville families still awaiting answers in the disappearances of their loved ones.

Many of the unsolved missing persons cases in Clarksville have gone cold for several years. Some date back as far as 1998, with the most recent missing persons case reported over two years ago in March 2020.

Those missing range in age from 20 to 59 years old, but many would be much older now. Each of their stories are similar in that they have vanished without a trace.

Shannon Elaine Arif

Shannon Elaine Arif was reported missing by her husband on March 17, 1998. At the time, her son was just 15 months old, and police believe she may have been newly pregnant. Her husband told police he last saw Arif at 9:45 a.m. before he left for work that morning.

Arif was scheduled to work at the Clarksville Walmart from 4:30 p.m. to 9:15 p.m. When she didn’t return home, her husband said he went to Walmart and found her car in the parking lot. The car was locked with her purse inside.

Walmart management said Arif never showed up for work that day. Following her disappearance, investigators searched the Walmart area with cadaver dogs, but found no trace of her.

Along with police, family and friends told News 2 they remembered passing out flyers hoping someone had information on what happened to Arif.

Some of Arif’s friends suspected her husband had something to do with her disappearance. In March 2022, police confirmed he was a person of interest in the case. However, no arrest has been made.

Shannon was 20 years old at the time of her disappearance. Investigators said she had blonde hair, blue eyes, was 5’4” tall and weighed around 100 lbs. Her husband said she was last seen wearing a red and blue Tommy Hilfiger shirt, jogging pants and Nike sneakers.

Mary Alice Cox

Mary Alice Cox was last seen in Clarksville on March 20, 2004, when she left her residence to walk to a nearby store. She was living in a group home on Vivian Drive at the time.

According to police, Cox suffered from schizophrenia, bipolar disorder and emphysema. She was supposed to take medication to control her condition but may have gone off it shortly before disappearing.

She had disappeared a few times before but was brought back by the police. Only days after Cox was last seen, her purse and medication were found on a riverbank about 10 miles from where she lived. However, there was no sign of her anywhere nearby.

Authorities do not suspect foul play in Cox’s disappearance. There have been unconfirmed sightings in the New Providence section of Clarksville and at her former home on Vivian Drive since her disappearance.

Police believe she could still be in the local area, in Florida, or in Nashville, where she has relatives.

Cox was 54 years old at the time of her disappearance. Investigators said she had brown hair, hazel eyes, was about 5’3″ to 5’5″ tall and weighed about 100 to 135 pounds. She was last seen wearing a wristwatch with a stretch band and possibly clip-on earrings and Keds sneakers.
