A security guard has been accused of trying to solicit a child online.

Jonathan Alexander Martinez, 25, was arrested at his apartment in the 3400 block of Woodchase in southwest Houston shortly before noon Monday.

Police said a 15-year-old runaway was inside Martinez's home when he was arrested. Sources said she is from north Texas and has been turned over to Harris County juvenile probation authorities.

The girl's parents told police they believe she took off with an adult she had met on the Internet.

Court documents show that in one of their online conversations he promised to pick up the girl; in another, he calls her his "wife". He then explained in detail what sexual acts he would perform on the girl.

Martinez has been charged with online solicitation of a minor and could face charges of having sex with a minor, depending on further investigations.

Records show Martinez has been working as a security guard more about a year and worked for Houston company, Securitas.
