Deangelo Martin, 34, who had already been reprimanded for four sexual harassment cases and one assault intending to murder, was held for allegedly killing four women on Detroit’s east side.

Prosecutor Kym Worthy announced on Monday that Martin will undergo trial for murdering four elderly women in Detroit at their vacant homes, USA Today reported.

The killings struck fear into people throughout metro Detroit in early June and other elderly people who might have been left in abandoned homes feared being a soft-target. The killer typically targeted women in their 50s.

The killer was recognized first as social media rumors started circulating but police had refuted them saying, “there is false information circulating” and “this is not true.”

The assassin was way younger than those victimized. They were first stabbed and then, were sexually assaulted. The first alleged murder victim of Martin was Annetta Nelson, 57, who was discovered in a pool of blood with her face down on the floor in a vacant house in Feb. 2018, Wayne County Prosecutor’s Office revealed as reported by ABC News. The prosecutor added that the police found a condom near her body. They then determined Nelson’s death to have been caused by blunt force trauma.

On March 19, in a similar incident, Nancy Harrison, 52, was found dead at another vacant house and her death was also a result of blunt force trauma, the prosecutor said.

Five days later after Harrison was killed, on March 24, Trevesene Willis, 55, was also found dead in her vacant home, her face down on the floor with a used condom thrown near her body, the prosecutor revealed. When police started probing into the matter as a possible murder followed by sexual assault, her decomposing body failed to supply evidence.

Then on June 5, Tamara Jones, 55, was found dead under relatable circumstances, her face down on the floor in a pool of blood with a used condom nearby, at a vacant house. Her cause of death could also not be unraveled as her body started decomposing by that time.

In a news conference on Wednesday, Wayne County Prosecutor Kym Worthy said, the crimes "struck fear in our community. We believe he is a serial killer," she said while talking about Martin.
