TRACY - "I know deep in my heart that she's alive and well. I just know that she's coming home back to us. I just pray that that happens soon," said Angie Chavez, Sandra Cantu's aunt. 

It has now been nearly one week since the Tracy girl went missing. Yellow ribbons are now tied around trees outside the eight year old's Tracy mobile home park where candle light vigils have been held every night since her disappearance. On Thursday night, the mother of Chandra Levy, who went missing eight years ago. attended the vigil. Susan Levy pleaded for Cantu's safe return.

"If anyone is out there that knows anything please have the heart and open yourself up, Be truthful and come forward and let us know what happened," said Levy.

Leads continue to pour in. Police have received more than 600 tips so far, but no arrests have been made.

"We're taking all leads, everything from family member tips to psychics. We're taking any lead that come in," said Lt. Jeremy Watney of the Tracy Police Department.

With boats and jet skis investigators searched up and down Old River north of town for clues. Search teams continue to sift through trash at the Tracy dump. They did recover a pink Hello Kitty T-shirt similar to the one Sandra was wearing when she disappeared.

"We found the Hello Kitty T-shirt yesterday that mom says wasn't her t-shirt. It was pink in color, very similar to what she was wearing. Her mom said it wasn't hers. We still retained it. We're still going to test it," said Lt. Watney.
