HOUSTON, Tex. (CBS/KHOU) -- It started with a sketch, now the man accused of raping several women in southwest Houston is behind bars. Police say his list of crimes is getting longer.

Investigators believe they have evidence that proves one young man is responsible for several attacks on women in southwest Houston.

Wearing an orange jumpsuit and handcuffs, Sedric Johnson made no claims of guilt or innocence to a Harris County judge. But outside the courtroom others did. One woman, afraid to show her face, is Johnson's girlfriend. She has an alibi. She says, "We've been working the whole time. All we do is work and come home. There is no play time. There's no nothing. He works from 6:00 in the morning all the way to 7:00 at night."

But prosecutors say Johnson's DNA matches that of a man who sexually assaulted three women in the last four weeks. Each attack happened at The Mills apartments.

Police say Johnson dragged women into vacant units at gunpoint, forcing each to perform oral sex. In two cases, police say Johnson had a lookout who hasn't been charged or caught.

A fourth woman claims Johnson attacked her too, stealing her purse.
This woman survived the first sexual attack. She says, "They said he was robbing people's purses, kicking in doors, he got what was coming to him, and hopefully he'll be in jail for a long time."

Prosecutor Alison Baimbridge says, "Each one of those women will never forget them. They will live them in their dreams and nightmares forever."

For that reason, at least two victims are suing owners of this complex claiming management should have offered better protection. Now, that burden falls on prosecutors who seem confident DNA evidence will at least convict the man in orange.

Johnson is being held Harris County's jail without bond. He was just arraigned Tuesday and has not made any pleas.
