A reward of up to $5,000 is being offered for information that leads to an arrest and indictment in the death of 36-year-old Megan Leigh Getrum.
Getrum's last known location was the Arbor Hills Nature Preserve in Plano, where she was messaging a family member after dark on Friday April 14; her body was recovered the next day in Lake Ray Hubbard.
Investigators searched the park after her disappearance and found no sign of any foul play.
Plano police spokesperson David Tilley said previously there are many questions that detectives are trying to answer, including how Getrum died and how she got to the lake 30 miles away without her car, identification or mobile phone.
Investigators said Getrum's car was found parked outside her apartment, which backs up to the preserve.
Police said previously they are treating Getrum's disappearance and death as suspicious. The Dallas County Medical Examiner's office is working to determine Getrum's cause and manner of death.
They released images last week of a red, yellow, and white floral-print bike shirt and green running shoes she was wearing when she disappeared, and police ask anyone who may have seen Getrum on April 14 or April 15 to contact investigators.
