Missing baby Lisa Irwin's parents could have another one of their children taken away from them, RadarOnline.com has learned, this time by the child's natural mother.

Blake Irwin's mom, Mrs. Rasleen Raim, has filed an “Emergency Motion for Temporary Custody” and “Motion to Modify Child Custody/Visitation” in the Circuit Court of Clay County, Liberty, Missouri, according to a letter released on Monday by her lawyer, Dorothy L. Savory.

The eight-year-old is the son of Jeremy Irwin, Lisa's dad, and Raim, who lost custody of him in 2008.

Missing baby Lisa Irwin turns 1 on Friday, as the investigation into her October 4 disappearance continues.

Kansas City police spokesman Steve Young told the AP the baby's two half-brothers were interviewed by child counselors Thursday, the latest effort in the search for the child.

The baby's parents, Jeremy Irwin and Deborah Bradley, have come under scrutiny for their own actions during the time their daughter was taken, and the rocky relationship they’ve had with the lawmen searching for their baby girl.

"I'm not saying they're not cooperating; they have met some of our needs," Young said. "What I've been talking about specifically is sitting down, separate from each other, to be interviewed by detectives. In regard to that, no, that hasn't happened since the 8th of October."

Add another mystery to the case of missing baby Lisa Irwin.

Cyndy Short, the Kansas City-based attorney working on behalf of Lisa's parents Deborah Bradley and Jeremy Irwin, is no longer representing the pair and is holding a a press conference Monday to explain why.

Short was the couple's local rep. High profile defense attorney Joe Tacopina from New York is also representing them.

As RadarOnline.com previously reported, the two attorneys had differing opinions on allowing Deborah's older children, who were in the house the night Lisa went missing, from being interviewed by the cops.

Short was opposed to it, while Tacopina wanted them to go forward. The scheduled interviews with the boys were canceled on Thursday.

In an emailed statement sent out Sunday, Short said that while she is no longer working for Lisa's parents, she and her team will "continue in the search for baby Lisa as concerned citizens."

Friday's scheduled police interviews with missing baby Lisa Irwin’s 8-and 5-year-old brothers have been indefinitely postponed, Radar Online.com has learned.

Parents Jeremy Irwin and Deborah Bradley have decided not to let the boys talk with authorities Friday, as the investigation into their 10-month-old's October 4 disappearance continues.

The boys -- who last spoke to police the night their sister mysteriously disappeared -- would have likely submit a DNA sample as well, officials said.

There's other problems in their camp, as two attorneys hired by the family -- Kansas City-based Cyndy Short and high-profile criminal attorney Joe Tacopina -- have expressed different opinions on if and when the interviews should happen.

As the police prepare to question Lisa Irwin's older brothers in an attempt for new insight from the family, private investigator Bill Stanton adamantly believes that the missing 11-month-old baby is still alive, RadarOnline.com has exclusively learned.

"Until they find a body, in my mind that baby is still out there and alive," Stanton told RadarOnline.com in an exclusive interview. "She didn’t just evaporate, someone took her."

As RadarOnline.com previously reported, Lisa’s parents Jeremy Irwin and Deborah Bradley have agreed to let the authorities question Lisa's big half-brothers, Michael, 5, and Blake, 8, on Friday about the night she went missing from the home.

Authorities have been saying that they are not getting the full cooperation from Baby Lisa Irwin’s family since she has gone missing. but her parents have finally agreed to allow her older brothers to be interviewed by the police.

The two boys, ages 6 and 8, will be questioned Friday by police about the night she went missing from the home and DNA swabs will be taken, according to an exclusive report on Good Morning America on Wednesday.

11-month-old Baby Lisa  has been missing from her home since October 4 and police have said they are not receiving the level of cooperation they want from her parents, Deborah Bradley and Jeremy Irwin. The parents counter through their attorney Joe Tacopina that they are willing to answer any questions from authorities, “As long as the investigators doing the questioning are ones who have not previously determined guilty before having a stitch of evidence. We want a fair investigation.”

There is a dramatic new clue in the case of missing baby Lisa Irwin.

Surveillance video taken the night the 11-month-old girl went missing shows a man coming out of a wooded area near the Irwin home at 2:30 am.  The video was obtained by ABC News which aired it Sunday on Good Morning America.

Police aren't yet commenting on the video but it may connect up with two independent eyewitnesses who told cops they saw a man carrying an infant while walking down the street that night.

Lisa was reported missing by her parents in the early hours of October 4 when her father Jeremy Irwin returned from a night shift at work, found the front door unlocked and Lisa gone. Her mother, Deborah Bradley, told the police she hadn't seen Lisa since she put her to bed at 6:30 pm the night before, and then drank until she was "drunk" with a friend.

The case of missing baby Lisa Irwin has some strikingly eerie parallels to another missing baby case, RadarOnline.com has learned.

In 2007, when Lisa's mother Deborah Bradley and her husband, Pvt. Sean Bradley were living at Fort Bragg, North Carolina, one of his 82nd Airborne unit mates had an infant disappear.

The baby's mother Johni Michelle Heuser reported to the police that her 11-month-old daughter had been taken.

She told the cops she'd last seen little Harmony Creech at 11:30 pm before going to bed. When she went to get the baby at 11 am the next morning, to see her dad Ronald Creech who had just just gotten off a plane after returning home from service in Iraq -- the baby was gone.

Investigators found a window open in the house and suspected a kidnapping.  An Amber Alert was issued.

Cops were always suspicious of Johni and within days she confessed to the baby's death. She said it was an accident she'd covered up out of fear her older children, from a previous relationship would be taken away.

Little Harmony's remains were found wrapped in a plastic diaper bag and hidden in the attic.

A jury didn't buy the accident defense. Heuser was convicted of second degree murder and sentenced to 11 to 15 years in prison.

Deborah Bradley and Jeremy Irwin reported their 11-month-old daughter Lisa missing when he returned from a night shift job at about 4 am on October 4. Deborah said she'd last seen the baby before she went to bed the night before. Their front door was found unlocked, they told cops.

An Amber Alert was issued and massive searches were undertaken near their Missouri home.

Deborah is still married to Sean Bradley and has a son with him, although she and Irwin have said they're engaged.

As RadarOnline.com previously reported, in documents filed to obtain a search warrant of her parents' home on Friday, it was revealed that an FBI cadaver dog got a "hit" inside the house several days earlier.

A FBI cadaver dog hunting for missing baby Lisa Irwin detected the scent of a dead body on the floor of her parent's bedroom, according to court documents filed on Friday, RadarOnline.com has learned.

The trained sniffer dog reported a "hit" on Monday inside the Kansas City, Missouri home where the 11-month-old baby was last seen in her crib on the evening of October 3, reported the Wichita Eagle.

The new development in the case that has captured the attention of the country was detailed in an affidavit that the police filed to support a request for a search warrant of the house, which resulted in an extensive search by police and federal investigators on Wednesday.

FBI, local police and crime dogs combed the home of missing baby Lisa Irwin Wednesday, after her parents Jeremy Irwin and Deborah Bradley, and the rest of her family, were barred from the property.

"We have a warrant for the house," Kansas City police spokesman Capt. Steve Young told the AP Wednesday as authorities proceeded with the latest phase of the investigation into the 10-month-old’s October 4 disappearance.

The entire area surrounding the home was blocked off with yellow tape, moving throngs of media at the house about a half-block back. FBI spokeswoman Bridget Patton said the media's restricted access was because officials did not want a procedure they're using (involving the dogs) filmed.
