A body found near Waco has been identified as that of a 21-year-old Southern Methodist University student reported missing Friday in Dallas, police said late Tuesday.

Construction workers found the body of Meaghan Bosch in a portable toilet in the 500 block of Connie Drive in Hewitt, authorities said. It appears she was placed there, and there were no obvious signs of trauma, authorities say. The medical examiner will determine the cause of death.

The last anyone heard from Ms. Bosch was about 4 p.m. Thursday, when she sent her ex-boyfriend a text message saying she was at the home of a drug dealer, according to her family.

Relatives said police questioned the dealer, and he admitted having lunch with Ms. Bosch about 2 or 3 p.m. but denied she was ever at his Dallas home.

Ms. Bosch missed a dinner appointment with her boyfriend Thursday night, and he informed her parents Friday that she never showed up, according to the family. Her parents then alerted Dallas police, who began investigating.

Ms. Bosch's truck was found at her off-campus apartment in the 6000 block of East University Boulevard near Skillman Street. The vehicle was unlocked and the keys were inside, police said. Her apartment was locked, her family said.

"The police don't think she was abducted because there were no signs of a struggle," said her father, Joseph Bosch.

"They think she may have gone off on her own or went with someone she knew."

He said the family noticed a change in her behavior about two months ago, when they learned she was using cocaine.

The Bosch family offered a $10,000 reward for information about her disappearance.
