(WPXI) -- Two people were found dead inside a McKeesport, Pennsylvania home Monday after a 7-year-old girl went to school and told someone that something was wrong with her parents.
The bodies of 26-year-old Christopher Dilly and 25-year-old Jessica Lally were found around 5 p.m. Monday.
Police said there was no foul play involved and that they suspect Dilly and Lally died of a drug overdose.
Three other children, ages 9 months, 3 and 5, were also living in the home.
Lally's sister said she tried to get help for the children months ago.
"My sister wasn't the person she became when it came to drugs. She wasn't the person I knew. It was like the drugs had taken over and at first we didn't know it was heroin," Courtney Lally said. "She loved her kids -- she did. She loved her mom, she loved me, she loved us."
