Bethany and Tina Sinclair
-- Last seen: Weekend of Feb. 3 and 4, 2001
-- Case status: Missing persons
Police said Tina Sinclair, 34, and her daughter Bethany, 15, disappeared soon after Tina had an argument with her boyfriend, Eugene Van Bowman.
Tina, a home nurse who had just finished cosmetology school, last went to her job on Feb. 2, 2001, the same day Bethany last went to school. Bethany also had her first movie date hours before she disappeared.
The pair were last seen together during the weekend of Feb. 3-4, 2001. Before the weekend, they lived at Bowman's riverfront home in West Chesterfield.
The two disappeared, with Tina leaving behind her car, her belongings and her pet cat.
The mystery deepened when, on Feb. 5, 2001, an unknown woman called Keene High School to report that Bethany would not be at class. Family members told WMUR in 2011 that they know who made the phone call but couldn't share the name because it's key to the police investigation.

Eugene Van Bowman
Family friends described Tina as carefree, happy and fun, and Bethany as the typical teenager who loved music and was a great student.
According to her sister, the family did not approve of Tina's "stormy" relationship with Bowman, who was a convicted sex offender.
Investigators searched Bowman's home and the river behind the home numerous times.
In 2014, dive teams searched a half-mile area around the Vernon Dam in nearby Vernon, Vermont, for any signs of the missing pair. Crews used side-scan sonar and sector sonar in the search.
Authorities did not say if any of the searches turned up any leads.
Authorities said they believe Tina and Bethany Sinclair are dead and died under suspicious circumstances.
Investigators consider Bowman the primary person of interest in the case.
