The investigation into the mysterious death of a Plano woman whose body was found in Lake Ray Hubbard last weekend is ongoing.
Megan Leigh Getrum, 36, was reported missing Tuesday after friends had been unable to reach her for several days.
Investigators began their search near the woman's last known location, at the Arbor Hills Nature Preserve on the 7000 block of West Parker Road in Plano, but found no sign of Getrum or of any foul play.
Plano police say Getrum was using her cell phone to message a family member from the park after dark on Friday night.
Dallas police confirmed an unidentified body found Saturday at about 7 a.m. at Lake Ray Hubbard had been identified as Getrum.
Investigators are working to determine how Getrum ended up more than 30 miles away from home without any identification.
Plano police spokesperson David Tilley said Thursday there are many questions that detectives are trying to answer including how Getrum died and how she got to the lake in the first place.
Her car was found parked outside her apartment which backs up to the preserve.
Police say they are treating Getrum's disappearance and death as suspicious. They released images Thursday 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 Friday night or Saturday morning to contact investigators.
Getrum's mother told NBC 5 off-camera she is puzzled by what's happened, just like everyone else.
"Everything that the family has told us, yes, this does appear to be out of character," Tilley said.
Police consider the case a "death investigation" not a homicide, though Tilley said they aren't ruling anything out.
Tilley said Getrum's phone has not been located.
The Dallas County Medical Examiner's office is working to determine Getrum's cause and manner of death.
"This could be something intentional, it could be something that was accidental or it could be something criminal and that’s what we don’t know," Tilley said.
