Investigators are looking to question a suspicious man seen on surveillance video near the California park where a 13-year-old girl was killed last week.

The body of Jessica Funk-Haslam was found in the dugout of a baseball field at Rosemont Park in Sacramento County on March 6. A coroner ruled that the girl was hit in the head, stabbed and asphyxiated. 

Police said during a press conference Thursday that they believe the child spent several hours in the park with someone she knew before being killed, Fox 40 reported. 

"I think she was there for some period of time with somebody she knew and was comfortable with," said Det. Tony Turnbull of the Sacramento County Sheriff's Department.

Turnbull also said investigators want to question an unidentified male seen running from the park at about the time the girl was killed.

The grainy surveillance video shows the individual ducking into a side street when a car approaches and then reemerging after the vehicle passes him. 

The girl's mother has said she left the family's home without permission, saying she was planning to meet someone but did not say whom. 

"She was wanting to go out see somebody. She wouldn’t tell me who. And yes, I got mad because I said it was getting dark," Tara Funk-Haslam told reporters last week. 

Friends described Jessica, a student at Albert Einstein Middle School, as a great actress who was kind to her classmates. 

"She was a good person and never mean to anybody," said one classmate.
