The search for 2-year-old Detroit girl Bianca Jones, who has been missing for five days now, continues without result so far. The child was reported missing on Friday morning, by her father, D'Andre Lane, who said his car was driven away by carjackers with Bianca strapped to the seat.

Extensive searches have been carried out, by both law enforcement officials and volunteers, encompassing the immediate neighborhood of the alleged kidnapping, including dumpsters and abandoned buildings. But the police have cautioned the volunteers to place personal safety above all else.

A lot of these abandoned homes haven't been searched and a lot of them [are] in bad shape, and we went in one house were gas was escaping, so we had to leave, myfoxdetroit.com quoted Bruce Knight, a volunteer, as saying, Some of these houses [have] dogs in them.

While searches go on, the police have not ruled out the possibility of Lane being involved in the disappearance of his daughter. According to reports on Fox 2 News, sources suggest that the police are investigating allegations that Lane beat his children. In fact, Lane himself believes that the police consider him suspect number one in Bianca's disappearance, according to MLive.com report.

Lane spoke on Tuesday, telling reporters that the villain in this case was the person who had taken Bianca away and not him. He said he wished for the safe return of his daughter.

Soon after everything happened I was talking to police and I heard some officers off to the side say, 'Oh, he has a criminal record,' said Lane, accompanied by his attorney, Terry L. Johnson, I know what that means. He has a criminal record. He's suspect number one.

I don't know what people are thinking. My main concern is my daughter coming home safely, he added.

According to Michigan prison records, Lane's record includes a prison sentence for possession of drugs and firearms, stemming from a 2003 arrest. He was granted parole in 2007. Lane has also served a probationary period of four years, from 1996 to 2000, for being convicted of assault with intent to commit armed robbery and a conspiracy charge.

Johnson, Lane's attorney, confirmed his client was held at the Oakland County Jail this weekend on an unrelated matter. Lane was, incidentally, ordered by the judge to attend anger management classes.

Meanwhile, Ralph Godbee, Detroit Police Chief, said Lane's story was under intense scrutiny by his investigators.

In response, Johnson also said that his main concern was the police's statement to the media that said Lane had failed a polygraph test.

This man has been vilified as public enemy number one. He needs someone to speak on his behalf. We're not saying he failed. We're saying it was administered improperly. You take someone under that kind of stress and put them in a room; he's not free to leave. He's in custody. He talks to you and now you want to strap him up to a machine. No one who gives a polygraph properly would do anything like that, the lawyer said.

Investigators have reportedly searched Lane's home and confiscated objects for further study. Lane has indicated that his family and he have received several threats over the past few days, as a result of which he will not be returning home immediately.

It's been told to me that it's in my best interest to just relax for a minute and kind of let things die down, he said, If something was to happen where (Bianca) comes home tomorrow and someone does something to me tonight, what would be the tragedy then?

The reward being offered for Bianca's return is $22,500.
