HOUSTON – A Houston teenager currently in jail for capital murder is now also being accused of committing two separate sexual assaults.

Police arrested Julius Merchant in May after they said he broke into a home during a burglary, shot and killed the homeowner, and pistol-whipped the man's wife.

David Macias was killed in the incident.

Now, investigators have linked Merchant, 18, to two sexual assaults.

Police said in April, Merchant broke into an apartment and allegedly assaulted a woman.

A few weeks later, police said he did it again.

Merchant, 18, is charged with capital murder, aggravated sexual assault and burglary with intent to commit felony.

He is being held without bond in the Harris County Jail. He's due in court Friday.

Court records show Merchant has a long criminal record, including charges of terroristic threat, criminal mischief and escape.
