Update: The suspect police were looking for has been arrested.
The 24-year-old was taken into custody in Missouri, Anoka County Sheriffs spokesperson Paul Sommer tweeted early Wednesday.
The 5-year-old girl (whose safety police were concerned about) was with him, "and is safe," Sommer said.
Note: Since authorities are no longer searching for the man, and he has not been charged with a crime, we've removed his names and photo from the story.
A young man is a person of interest in the death of a toddler, and authorities believe he has fled with a 5-year-old.
The child, 21 months old, died after life-saving efforts at Blaine Medical Center Tuesday morning, according to the Anoka County Sheriff's Office.
The child's mother was also at the hospital and is cooperating, and the sheriff's office said a home in the area is also being investigated.
Meanwhile they're looking to question a 24-year-old in connection with the case.
Authorities also think a 5-year-old girl is with him.
"There are grave safety concerns for the 5-year-old," the release said, noting the man is not a relative, nor does he have custody of the girl. Police think he might be trying to get out of the Twin Cities area.
He was last seen leaving an Arden Hills address at 9:30 this morning. He was wearing a black T-shirt and jeans. They don't know what vehicle he might be in.
The girl was wearing a brown and black jacket with purple pants, and brown shoes.
He has not been charged with any crime in connection with this case.
If anyone knows anything, or sees the the man and/or child, they're asked to call Blaine police or the Anoka County Sheriff's Office at 763-427-1212.
More on abductions
It is more common for a child to be abducted by a known person than a total stranger, according to Parents.com.
Studies have found that in child abduction cases, almost half (49 percent) are carried out by a relative of the victim, known as a “family kidnapping,” while 27 percent are carried out by acquaintances of the victim.
The remaining 24 percent of kidnappings are carried out by strangers. According to Forensic Psych, 95 percent of stranger abductions are carried out by men.
Child abuse in Minnesota
In Minnesota, child protective services responded to 19,602 accepted reports of maltreatment involving 25,297 children in 2013, Prevent Child Abuse Minnesota says.
Lawmakers have been looking for ways to improve Minnesota’s child protection services after a string of high-profile critical investigations and reports, specifically the tragic case Eric Dean. In 2015, lawmakers did pass new protective measures.
More than 700,000 children were victims of maltreatment in the United States in 2014, the U.S. Department of Health and Human Services says, while 1,580 children die as a result of abuse every year – a rate that’s higher than those who die from childhood cancer.
