"The officers were shocked because they had an appointment with her [to pick her up]," said Taylorsville police Sgt. Rosie Rivera.
The drugs could result in additional charges against the 22-year-old mother, Rivera said.
Lacey was charged Wednesday with abuse or desecration of a dead body, a third-degree felony, for allegedly transporting her deceased daughter, Estella Jean Lacey, from her boyfriend's Taylorsville home to her Murray residence.
The boyfriend, Raymond D. Chesley, 43, was charged with first-degree felony child endangerment as well as abuse or desecration of a a dead human body, a third-degree felony.
Chesley's actions allegedly led to the child's death, according to documents filed in 3rd District Court.
On the afternoon of Dec. 27, Chesley and the sleeping child were on a couch as Chesley prepared to ingest some meth from a plastic baggie, according to charges.
But Chesley was interrupted when his father, who lived upstairs, called to him.
Chesley told police he put the baggie on the armrest of the couch within reach of the baby and went to speak to his father.
When Chesley returned, the baby had the baggie in her mouth. He told police he removed the baggie, but the drugs had dissolved in the child's saliva.
The child reacted by becoming hyperactive and crying for hours, according to a police affidavit. The next morning, Chesley and Lacey noticed the child was dead.
Police said the child could have been saved if the defendants had summoned help while she was still alive.
They took the body to Lacey's Murray home to avoid having police come to the Taylorsville residence where Chesley and his father lived.
Chesley is on parole from Colorado for several crimes. His criminal record includes convictions for menacing, carrying a concealed weapon, criminal mischief and driving under the influence.
At Lacey's home, the defendants laid the dead baby on a bed, then Lacey called 911, according to the police affidavit.
An autopsy showed the baby died from "methamphetamine poisoning."
On Wednesday, Chesley was booked into the Salt Lake County jail, where he was being held in lieu of $1 million bail.
Lacey's bail was set at $20,000.
