City officials alerted the police when the mayor failed to show up at a scheduled meeting, according to CBS/AP reports.
Police found the bodies of Peters, 55, and her daughter,19, in their Dallas suburban home.
The police believe
Peters shot her daughter in the head before turning the gun on herself. There is no clear motive, and the case remains under investigation, but four notes were left behind
and there was no forced entry into the home.
The first of the four notes contained a key to the front door and a warning to whomever entered the home that what they were about to find would not be pleasant. The other notes left instructions for taking care of the family's affairs and the pets, but did not shed light on the reason for the mayor's actions.
The mayor's husband, Donald, died in 2008.
City officials and friends are wondering what prompted the incident. As of Thursday morning, the City of Coppell website
featured a short statement which reads: In Memory of Jayne Peters (1955 - 2010) Served the City Well, Dedicated City Servant from 1998-2010.
Peters was elected mayor of the city of 40,000 in 2009 and had served on the city council prior to becoming mayor. Peters was a former software developer and a graduate of Miami University of Ohio. Corinne Peters was a recent high school graduate with plans to attend the University of Texas in Austin.
