The Tribune Review reported that Lartz's mother, Bruna Vesco Leonard, said her daughter had been at the home visiting a friend. She said Lartz was "trying to get a better life, to get out of Jeannette" and live in a house in the country, planning to support herself and her two children by opening a landscaping firm and a home cleaning business.

"Her kids were everything to her. What will they do without their mom?" Leonard said before crying and hugging her husband, Joe Leonard, the paper reported.
