A Plano man arrested in the rape and strangulation of a woman near Texas Christian University last month went on to kill a Plano woman whose body was found in Lake Ray Hubbard days later, police said Friday.

Police say Reginald Kimbro, 23, has also been linked to at least two previous rapes, but he was never prosecuted. They are now looking from Dallas-Fort Worth to Arkansas for other possible murder or sexual assault victims.

Megan Leigh Getrum

Kimbro was arrested April 27 and later charged with capital murder in the death of Molly Matheson, 22, of Fort Worth. He now faces an additional capital murder charge in the death of Megan Leigh Getrum, 36, of Plano. Prosecutors in Tarrant and Dallas counties could seek the death penalty.

Kimbro and Matheson dated briefly, but Kimbro and Getrum were strangers, police say. Both women were raped and strangled.

Law enforcement is "backtracking" where Kimbro has been, Plano police spokesman David Tilley said. The department is asking local law enforcement in two states to examine unsolved murders, missing person cases and sexual assaults similar to those Kimbro is accused of committing.

"We had the one, and then we had two," Tilley said. "Where there's two, there could be three."

Tilley also said some rape victims could have been fearful of reporting crimes to police because Kimbro is a "dangerous" man.

"There may be people out there who may have been scared to come forward. Now he's locked up, and he's probably not getting out," Tilley said.

Kimbro denied that he killed either woman, police say. His attorney could not be reached for comment.

Both victims were raped

An arrest warrant affidavit released Friday said Kimbro's DNA was found on both Matheson's and Getrum's bodies.

Plano police believe Matheson was sexually assaulted and strangled on April 10. They said her killer tried to get rid of evidence by washing her body at her Fort Worth apartment.

Four days later, Getrum left her Plano home for a walk in a park and never came back. On April 15, her body was found nearly 30 miles away in Lake Ray Hubbard, but it would not be identified until April 19, a day after her family reported her missing.

The medical examiner concluded she died of homicidal violence that included blunt force injury, neck compression and drowning, court records show.

A sexual assault exam found Kimbro's DNA, the records say.

During the investigation of Matheson's murder, Kimbro told police he had been in her room shortly before her death. He denied killing or raping her.

Kimbro's Facebook page, which has been deactivated, said he lived in Plano and was a marketing student at the University of Arkansas, where Matheson went to school. The university, however, said last month that it had no record of him being a student.

Matheson's family released a statement Friday afternoon saying they were saddened by the latest accusations against Kimbro.

"It is extraordinarily frustrating to know that neither of these senseless murders should have ever happened if our judicial system had done its job properly," the statement read.

The worst part is we are no longer the only family involved. The Getrum family is in our prayers. — Lord Grandpa (@Lord_Grandpa) May 26, 2017

Never prosecuted for rapes

Kimbro has been the suspect in at least two other sexual assault investigations in the past, but those investigations didn't result in any charges against him.

In 2012, a woman in Plano accused him of throwing her to the ground and sexually assaulting her as he choked her. Police said he then ordered her to get into the trunk of his car. She promised not to tell anyone what happened, but reported the alleged incident to police when she got home.

Plano police didn't file any charges against Kimbro at the time because the woman said she didn't want to pursue a case.

A girlfriend of Kimbro's told Plano police in 2014 that he liked to "strangle" her while they had sex. She "would then have to remove his hands away from her neck because he had, 'gone too far,'" the arrest affidavit released Friday says.

In 2014, police in South Padre Island arrested Kimbro after a woman said he raped her and choked her. His DNA matched samples collected from the woman in a rape examination, but authorities there didn't pursue a case against him, Plano police wrote in their arrest affidavit for the Getrum case.

South Padre Island police and the Cameron County district attorney's office could not be reached for comment about why the case did not move forward.

Kimbro's father, Eugene Reginald Kembro, was convicted of voluntary manslaughter in 1994 in Dallas County. He pleaded guilty and was sentenced to 10 years in prison. The father was originally charged with murder. Details about what happened weren't immediately available.

The father also has convictions in Dallas County for burglary, DWI, drug possession and being a felon unlawfully possessing a gun.
