BOCA RATON, Fla. -- Authorities are investigating a tip that a suspicious male resembling the sketch of the Boca Town Center murders suspect may have been at Aventura Mall recently.

Boca Raton Police spokeswoman Sandra Boonenberg says her agency has seen the surveillance video from the Miami-area mall and says there is a resemblance. But she also points out that they have received dozens of similar tips.

The video shows the suspicious male following a woman and her child on April 30th at Aventura Mall.

The bodies of a mother and her daughter were discovered in their car outside the Boca mall in December. They were bound and shot to death.

No arrests have been made. The city is offering a $350,000 reward.

A similar attack occurred at the Boca mall in August.
