Parents of missing San Diego girl offer $25,000 reward, volunteers search area for Danielle

SAN DIEGO - The parents of a girl who vanished from her bedroom more than a week ago offered a $25,000 reward Monday for information leading to her return. <br> <br> Brenda and Damon van Dam said they hoped the offer would help sustain national attention on the case and lead to a breakthrough in the investigation. <br> <br> &#34;We pray for Danielle each night,&#34; Brenda van Dam told reporters outside their home. &#34;We&#39;re very emotionally drained.&#34; <br> <br> The family has not seen 7-year-old Danielle since Damon van Dam put her to bed on Feb. 1. She was discovered missing the next morning. Police believe she was abducted. <br> <br> Hundreds of volunteers continued to help authorities in the search for the second-grade girl. <br> <br> The search effort, led by the Texas-based Laura Recovery Center Foundation, drew 300 volunteers Saturday who covered a 25-mile radius around the van Dam family home in the suburb of Sabre Springs. More than 125 people searched Sunday in areas closer to the family&#39;s house. <br> <br> Investigators have seized a motor home and property belonging to a neighbor. He has allowed police to search his home. No arrests have been made. <br>
