LANSING — Police say a DNA test released Friday shows the dead infant found in a Roseville recycling plant is not the son of a Meridian Township woman charged with killing her firstborn.

On Tuesday, Mitin told court officials she doesn't know the location of her second baby. Meridian Township police Lt. Greg Frenger said Friday police are still searching for that child and hope to find the child alive and well.

Roseville police Chief James Berlin said earlier Friday afternoon it appeared the baby found in the recycling center belonged to Melissa Mitin, 25 of Meridian Township. However, shortly after that statement, Roseville police issued a statement saying the DNA test showed that wasn't the case.

“The child we have does not belong to Melissa Mitin,” Berlin said. “Her child is still missing.”

It’s a case that has shocked many in the Lansing area. News broke on Wednesday that Mitin, charged with leaving her first child to die in a trash bin on Dec. 26, 2013, had this week told court officials she had been pregnant, delivered a baby and didn’t know where the child was located.

Mitin was charged with open murder and concealing the death of a child in the first case. After being charged, Mitin was given a 10 percent of $50,000 bond, meaning she was able to leave jail for $5,000 despite the fact that she was charged with murder.

Ingham County Prosecutor Stuart Dunnings III said prosecutors learned Monday that Mitin had been pregnant.

Mitin, who had concealed her pregnancy prior to the death of her first child, apparently did not inform anyone connected to the case that she was pregnant with another child, Dunnings said. On Tuesday, in a family court hearing, Mitin said she had given birth and was not aware of the whereabouts of that child.

Mitin’s bond was revoked and she’s now being held in the Ingham County Jail. A competency exam has been ordered, and that could take up to three months to complete. She was scheduled to face trial in February.

“I’m kind of sick,” Berlin said before the results came back. “I hope it is hers, instead of having two mothers out there who killed their child.”

The baby found in Roseville could potentially have come from the Lansing area, Berlin said.

Berlin said Roseville police received a 911 call on Wednesday night alerting them to the discovery of a dead baby boy at the recycling plant.

The recycling center in question takes shipments from all over Michigan in large dumpsters, some of them about 20 yards long, Berlin said. He said the dumpsters are emptied into a machine that puts them onto a conveyer belt for workers to sort them into separate containers.

The dumpsters came from 34 different locations around the state and Roseville police are now checking with each of those locations, Berlin said.

He said an employee saw something wrapped in a T-shirt-like material. The employee grabbed the bundle, unwrapped it and the body of a dead infant baby boy fell out, Berlin said.

“The average person doesn’t know how to deal with that, and thankfully doesn’t have to deal with it that often,” he said, when asked about the employee’s mental state.

The case has been upsetting for many in the Roseville Police Department. Many of the officers there are parents themselves, Berlin said.

Anyone with information on Mitin’s whereabouts within the last few weeks or who might have seen her with a child is encouraged to call the Meridian Township Police Department at 517-332-6526.

Anyone with information about a person who might have given birth within in the last two weeks who has not been seen with their baby recently is encouraged to call the Roseville police at 586-447-4483.

Frank Reynolds, Mitin's attorney, said her family is very worried about her mental state.

"The Mitin family is very distressed about this situation," Reynold said in a statement. "They are extremely concerned about their daughter. They have had many media requests and some media have shown up at their home. At this time they do not wish to do any interviews as they continue to try to understand and cope with this situation."

Reynolds said there is no additional information for him to release and he declined further comment.
